RE: IMAGES/PICTURES-MYSQL
Hi! I have seen in this page http://www.blobstreaming.org/ but i think that it´s quite difficult. I want to put only the url of the image, and as you said the pictures o images might be in the server folder, but what is the folder?

RE: IMAGES/PICTURES-MYSQL
It all comes down to what you are most comfortable with. What I have done is to name each image file with a serial number (1.jpg, 2.gif, 3.png, ...) and store the path along with the "real" name of the image in a table row. Doing it this way means that you don't need to program logic to convert a blob in order to serve it up with a script, you just need to programmatically create a link to the image file and let the web server do it. I find that easier to work with, and certainly easier to debug.

How are you storing the image in MySQL..I assume longblob?
What format will you use to display the image {jpg|gif|png}?

Re: Images
Tons of caching options.. tried quite a few.. - squid/similar proxy.. - the image streaming/serving script stores the image in /tmp, if the script next time sees the time file (perhaps using databaseid.img filename format) it serves it from disk.. maybe checking the last changed timestamp or something - written a custom caching servlet to request the image from db once, and then serve it from memory for a pre-determined cache time, at which point it re-request/re-caches new object in memory..

RE: Images
I read through the article and ran some more tests. The new scripts and tables provide similar initial latency, but I think the test results show them to be faster overall. When it comes to latency, direct file access is still the champion without caching. I think you made a good point about throughput which makes MySQL more appealing for storing larger files. That kind of surprised me actually, because I always figured I'd have to store things like PDF's on disk and control access to them by putting them outside of the document root. There's still a question of whether caching provides the edge and at what cost. I haven't set up caching, so I'm not sure if it's complicated or not. It would provide performance boosts to more than just images through, so it seems worthwhile to explore. That's what I'll be exploring next. =) -Ed > -Original Message- > Most people make the mistake of using the biggest blob size to store > files..

Great .. I don't have any numbers.. but basically there is quite little latency using the FTP interface, data is streamed in and out of mysql on the fly, inserting and selecting blocks of rows..

RE: Images
Ok... I have some more test results. After optimizing as much as I can think of, without using caching, I've gotten things down to a 13x difference. Using Apache's ab performance test, the image comes from a file at an average of 2ms and from the database (using PHP4) at an average of 28ms. I know... it just reiterates what you were already saying, but it sure is great to see actual numbers measuring the difference. Maybe the difference could be even less if I were properly optimizing MySQL. The big question still outstanding, for me at least, is whether web page caching makes the performance difference a mute point. If caching is storing everything as files, we get the best of both worlds. Plus, I think there may be a little bit of a security benefit. A directory has to be marked as writeable so that scripts can store image files. This isn't necessary when using MySQL. Do you agree with the security benefit? Does webpage caching negate the performance difference? -Ed > -Original Message- > Grabbing the file was 38 times faster because MySQL was not designed > to be a filesystem.

Re: Images
Most people make the mistake of using the biggest blob size to store files.. That blob size is capable of storing just HUGE files..What we do is store files in 64K (medium blob) chunks.. So if the image was say 200K in size, the metadata for the image would be 1 row in a table, and the image data would be 4 rows in the data table. 3 full 64K rows + 1 partially used rows. There is a good article/sample code here on the kind of technique we started with: http://php.dreamwerx.net/forums/viewtopic.php?t=6 Using chunked data, apache/php only needs to pull row by row(64k) and deliver to the client, keeping the resultset size low = memory overhead low. The storage servers (mysql storage) I have tested on the LAN; them storing and retreiving data from mysql (using FTP gateway) at rates of 4600K/sec.. which is I think the fastest speed my laptop network card could deliver. That's pretty fast.. Rare day when most internet users can talk to servers at those speeds.

RE: Images
Thanks for the link =) I understand what you're saying about MySQL not being designed as a filesystem. I've used this same argument with others. It's just that... well, have performance boosts have decreased the margin of difference? Especially when web-page caching is being used - don't the images get cached as actual files? If so, the original method of storage would be a mute point. That's what I'm trying to find out.

I agree. That's the approach I used. Data on products are stored in a products table, while images are stored in a table called images. The images table has the following fields: ID, ProductID, SizeID, Image. There are 4 images of different resolutions for each product. The SizeID is used to tell which resolution is being requested. For example: Select Image from images where ProductID='8443' AND SizeID='1' ProductID is an int. SizeID is a small int. The Image field is largeblob, because some images are as large as 300k. However, images are generally 15k, 45k, 90k, and 180k, so perhaps largeblob is causing a performance loss? I also plan on using caching tools, so maybe performance tuning on the backend isn't as significant? What do you think? -Ed -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

RE: Images
What do you mean "chunked"? I figured it would be easier to track about 32,000 images in MySQL than in files, so I setup a test to see what the performance difference is and if storing in MySQL would actually work. Everything is working and it's a lot easier to keep track of the images in MySQL. I ran some performance tests using Apache's ab though and there's a huge performance difference - 38 times faster grabbing the file. It could be my test system here at home. I've asked my ISP to upgrade my production server to PHP5 so that I can run tests from there. There could also be performance hits in the script that grabs the images from MySQL, because I tried using OOP. I was told OOP would be a faster approach, but I'm pretty new to it and may not have done something correctly. I'm going to create some non-OOP scripts to cross-reference the tests. I only have one production server, so I won't be able to separate / dedicate servers. Your mention of chunking sounds promising though. Actually, I'd appreciate any ideas or recommendations you have.

RE: images from MySQL backend used with MS-Access 2000 frontend
I would recommend storing the images on the filesystem and put the information about those images (along with the path to the image) in MySQL. If you plan to have lots of images, implement a nice logical directory structure to keep them in as in my experience linux ext2/3 is fast reading/writing files in that scenario and can be slow in retrieving files in a single directory containing large amounts of files.

Be warned about hitting the default max_packet_size limitation of mysql
which will cause large files to not insert.

Here is a sample code in PHP:
$image = file_get_contents('/tmp/my_image.png');
$res = mysql_query('insert into img_table ( data ) values

Works with a table like:
create table img_table (bigint not null auto_increment primary key, data
LONGBLOB not null default '');

Re: images on database
The most common problem in such cases is that the webserver doesn't know what MIME Type the file is and so it doesn't know how to send it. If you are using PHP to upload and later show that image on the web, i could give you the code for the scripts and the structure of the table containg the binary data.

Re: images with mysql
Not an issue since you don't need to edit the htaccess file for every file. You set it for the whole directory. The only reason for preventing ppl to access files would be theft of bandwith. If you worry about ppl being able to get the images then you shouldn't publish them at all. You can't protect them from being dumped with printscreen. Another solution would be to change the the path at random and copy all images to the new location while you copy a special image on the old location. You have no idea how fast ppl will stop using your pics if they have the text "stolen from ..." where you put your domainname on the dots. This would require you to have the path to the file in your code. HTTP REFERER is not always set correctly so I wouldn't trust that to much. B. At 09:13 21-03-2003 +0100, lasse wrote: sure you can.

Don't forget that the images can be stored *outside* the root dir. Access them using ../../ until you reach your img dir. There's no way to get to the images directly then.

Re: images with mysql
You can use other ways to protect your images from linking by others. Like with Apache and htaccess.. I don't agree with you on your opinion that it's easier to code. If you insert a link into your database all you have to do is retrieve it and push the link to the browser. B. At 20:18 20-03-2003 +0100, lasse wrote: hey all.. new to the list. Just my 5 cents...

Re: images with mysql
I assume it is, have not tested it.. If you need to fetch the files from the database your app needs to wait until it has recieved the data. If you only store name/path info it will take less time to fetch the data, ship it off to the browser which can start fetching the images without connecting to the database again. Sounds pretty logical.. and it gets worse if your site is hosted by an ISP who is using a database server running on a seperate box.. B.

Would it still be faster to store them on > disk? > In most cases yes. We have over 3.5 million images stored and mananaging them from the database side would be almost impossible. There are many benifits to using the file system instead of the database. 1. You can archive the images on cd/dvd/tape as new ones are received/added. 2. Try converting or moving databases with 200GB of blob files. 3. The larger the database, the longer it takes to retreive information. 4. Data from a database is retreived one row at a time so you have to wait for each image. Storing the path in the database allows you to fetch a row, spawn a child process to fetch the image, and continue to fetch rows from the database while the child processes handle getting the images. 5. Mysql will not cache the images. The OS however will cache disk reads. 6. The database has a finite set of resources. You can add many file servers, each specific to what "type" of image you're pulling. We store stuff by date so we know to pull 1998 images from fileserver a and 1999 images from fileserver b, etc... The OS on each fileserver can then cache what is requested most often.

Re: images with mysql
Well, this may be off topic. In my case, I store tens of thousands of images, gradually growing. All of them are quite small, most around 30*30 gray scale. Would it still be faster to store them on disk?

Re: images with mysql
IMHO it's better to store a link. I have seen databases (not MySQL) getting corrupted because the file inserted was to big. For the visitor it doesn't really matter whether you put it into the database or not. A link is less difficult and you don't have to retrieve pictures from the database so it might be quicker.. B.

RE: images with mysql
I had a go with putting a image into MySQL and it did not work. But what I did do is put the directory and image location "/image/smile.jpg". This is very good way to use the index of the db and the speed of the file structure. Sorry if this was not what you were looking for but I hope it helps a bit.

RE: Images in MySql
Eric, Generally you would store references to the images in the database as a full or partial pathname. You can store binary data in the db itself using the BLOB type but this is not necessarily the most efficient approach to take John Lodge -Original Message- From: Eric Torr Klopper [mailto:[EMAIL PROTECTED]] Sent: Monday, January 28, 2002 12:31 PM To: [EMAIL PROTECTED] Subject: Images in MySql Hi all.
