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
Hello!
I have tried the instructions that you explain to me. I have read also some
issues but doens´t work.
So i have done:
ui:tableColumn binding=#{STOCKSOC.tableColumn6} headerText=image
id=tableColumn6 sort=producto.image
ui:imageHyperlink
action=#{STOCKSOC.imageHyperlink1_action}
binding=#{STOCKSOC.imageHyperlink1} id=imageHyperlink1
imageURL=C:\Documents and
Settings\Ibai
Leizea\Escritorio\gsg\SociedadGastronomica\web\IMAGES\im?imageid=#{currentRow.value['producto.id_prod']}
text= url=C:\Documents and
Settings\Ibai
Leizea\Escritorio\gsg\SociedadGastronomica\web\IMAGES\im?imageid=#{currentRow.value['producto.id_prod']}/
/ui:tableColumn

http://www.nabble.com/file/p13894350/2.jpg
http://www.nabble.com/file/p13894350/3.jpg
I don´t know if my proyect is in the correct path (C:\Documents and
Settings\Ibai Leizea\Escritorio\gsg\SociedadGastronomica\) or the images
(C:\Documents and Settings\Ibai
Leizea\Escritorio\gsg\SociedadGastronomica\web\IMAGES). I have also proved
copying the IMAGE folder in other path, but it doesn´t work. I don´t know
specifically which is the server path.
Thanks to everybody!
Ibai

Re: IMAGES/PICTURES-MYSQL
Hi, I have read some messages about this topic but i haven´t resolved my problem yet. I am using mySQL Query Browser to make de schema. And i have a table (product) where there are some attributes (producto, precio, nUds,tipo)(spanish). All are relationated with one product (ex: heineken beer). So, i want to put another atribute image where i can put the image of all the products. But i have read that is imposible, that i have to put the path of the jpeg or gif, but i don´t know how. If anyone could help me i will be grateful. Attached is the image of my DB: What makes you think it's impossible to store the actual image inside a blob field?

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.

Re: Images to MySql Database in PHP or JAVA
Hi, Have you try google ? http://www.google.fr/search?hl=frq=storing+image+in+mysqlbtnG=Recherche+Googlemeta= I see pretty much a lot of stuff there ;) btw, storing image in a table in considering a bad practice, let the filesystem handle it it does it more efficiently. I would suggesdt to write the image on the disk, and then store the path in you db with useful thing like image format, width, height, etc... HIMH.

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.

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
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.

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
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.

Re: images with mysql
hey all.. new to the list. Just my 5 cents... I think it's better to store images in the database, sure you loose a bit in performance, but it's easier to code. The way i've done it before is always a separate render.php (or what ever) that compares the users rights to view that image, get's the blob from the database, sets right content-type for the page and then renders the binary data. That way... you can control frames/design (direct links to images can be avoided) und so weiter... //lars On Thu, 20 Mar 2003, B. van Ouwerkerk wrote: I assume it is, have not tested it..

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 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. Eric here from South Africa. I'm fairly new at using mysql and need to access images via a php website. What is the best way to store images or reference to images like jpg and gifs in a mysql db?

Re: images and mysql
This topic has been discussed many times on the PHP General (archived at http://marc.theaimsgroup.com/?l=php-general) and PHP DB (archived at http://marc.theaimsgroup.com/?l=php-db) mailing lists.
