I think it has to do with the imagealphablending. Any ideas? TIA Karl DeSaulniers Design Drumm http://designdrumm.com If it's just that the images are different sizes, then imagecopyresample might be the better option.

Tony, You might want to try the online php manual, I hear it's very good. You should be able to do all of the tasks you desire. Look for image in your search. Hope this helps.

First, why store it in a database? Why not store it as a separate file, then store pointer/file-name to it in database?

Re: [PHP] Image Question
Could it be you're unwittingly converting the graphic into 8bit color? That's certainly what it looks like. I've read that older versions of PHP and GD library don't always translate color depth. I don't have much experience programming graphics in PHP but I thought I'd offer up this possiblity.

Re: [PHP] Image Question
I'm putting it in the database because it's easier to handle that way, my site doesn't get too much traffic so it's not that big a load, and the files are usually between 2-8k which is tiny and the server should be able to handle that. Anyway, I have to resize the image because some of my writers don't know the first thing about image editing and can't resize the image themselves. - Original Message - From: Rick Emery [EMAIL PROTECTED] To: 'Jay Paulson' [EMAIL PROTECTED]; [EMAIL PROTECTED] Sent: Monday, April 08, 2002 5:19 PM Subject: RE: [PHP] Image Question First, why store it in a database?
