I agree that with strict image security it is an option. Give an image only to particular people, etc. But data management? I don't think so, but let's just my opinion. Image security is probably the only practical example I can think of for doing this, but there again Derrick isn't going for that. As far as having html text and the image binary on the same 'page'...I've never send that before. John [EMAIL PROTECTED]

Derrick started this whole discussion on the BlueDragon Interest list. I guess he brought it here because no one could tell him a technique for doing what he wanted on that list. But over there just as here, people asked the "why would you do that?" question about storing images in the DB. An good rule of thumb was put forth: if it's "page furniture," keep it in the file system; if it's data, keep it in the DB. If it's data, use your data management tool (a.k.a. your database) to manage it--why reinvent the wheel? On the security side of things, note that by using <img src=".../myheaderimage.cfm">, you can implement all the same security you would for any other resource your app serves up.

There might be a rare case now and then for doing this, but really you should probably just use the filesystem for what it's design for, storing files.

Sent: Thursday, January 18, 2007 10:22 AM To: discussion@acfug.org Subject: RE: [ACFUG Discuss] Image from DB I'm just curious. What are the benefits of storing the image in the db rather than storing the file on the filesystem and the path in the db? I mean, for a web page, all you need is the <img> and the path. I can understand how it might be useful in some VB or C or Java app where the client doesn't display images with such ease, but for a web app...? Thanks. mf -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of John Mason Sent: Thursday, January 18, 2007 10:16 AM To: discussion@acfug.org Subject: RE: [ACFUG Discuss] Image from DB I believe there would still be three http requests here. The images would still be called up in the html like <img src=""> right? Sorry but in http that would still create seperate http requests. John [EMAIL PROTECTED] _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Derrick Peavy Sent: Thursday, January 18, 2007 9:35 AM To: discussion@acfug.org Subject: [ACFUG Discuss] Image from DB Probably an easy problem for someone... I want to put two small images in my database and then output them in my app, so that they do not constitute additional http requests. Consider it an experiment - I know that it may seem a bit silly. The goal is for the entire page to be delivered to the browser in one http request, instead of 3 (two images and one cf page) without doing any Apache tinkering. I have looked around the net for answers and cannot seem to make this work. Database field is "imageFile" of type BLOB in MySQL 4.1.13. What is the proper way to insert the image? Example: INSERT into Images (imageFile) values ('#base64(image)#') -Or- Example: INSERT into Images (imageFile) values ('#image#') And then of course, how do you retrieve it? Example: SELECT imageFile FROM Images WHERE imageID=1 <cfoutput> #toString(imageFile)# </cfoutput> -OR- <cfoutput> #toBinary(imageFile)# </cfoutput> As I say, I've not been able to make this work. If I use toString(), I simply get the raw data. If I use toBinary(), I get an error that the data cannot be converted to a string. Also, using CFCONTENT is fine to output the image, but then any code after that is ignored. So, short of saving the entire page and then outputting, it, I don't see a way to use CFCONTENT. _____________ Derrick Peavy Sales and Web Services Universal Advertising Phone: 404-786-5036 Fax: 404-370-0470 http://www.universaladvertising.com http://www.collegeadvertising.com http://www.collegeclassifieds.com ___________________________________ ------------------------------------------------------------- To unsubscribe from this list, manage your profile @ http://www.acfug.org?fa=login.edituserform For more info, see http://www.acfug.org/mailinglists Archive @ http://www.mail-archive.com/discussion%40acfug.org/ List hosted by FusionLink <http://www.fusionlink.com> ------------------------------------------------------------- ------------------------------------------------------------- To unsubscribe from this list, manage your profile @ http://www.acfug.org?fa=login.edituserform For more info, see http://www.acfug.org/mailinglists Archive @ http://www.mail-archive.com/discussion%40acfug.org/ List hosted by FusionLink <http://www.fusionlink.com> ------------------------------------------------------------- ------------------------------------------------------------- To unsubscribe from this list, manage your profile @ http://www.acfug.org?fa=login.edituserform For more info, see http://www.acfug.org/mailinglists Archive @ http://www.mail-archive.com/discussion%40acfug.org/ List hosted by FusionLink <http://www.fusionlink.com> ------------------------------------------------------------- ------------------------------------------------------------- To unsubscribe from this list, manage your profile @ http://www.acfug.org?fa=login.edituserform For more info, see http://www.acfug.org/mailinglists Archive @ http://www.mail-archive.com/discussion%40acfug.org/ List hosted by FusionLink <http://www.fusionlink.com> ------------------------------------------------------------- ------------------------------------------------------------- To unsubscribe from this list, manage your profile @ http://www.acfug.org?fa=login.edituserform For more info, see http://www.acfug.org/mailinglists Archive @ http://www.mail-archive.com/discussion%40acfug.org/ List hosted by http://www.fusionlink.com -------------------------------------------------------------
