Post if you get stuck. :-) Don't forget the ENCTYPE part!!! For scaling the image, there are several options. One is to force the user to only submit images that fit within a certain size/parameters. This is probably good to avoid people uploading HUUUUUGE image files. You also should add some code in your file upload to be *SURE* it *is* a valid image, so your server does not become a clearing-house for the latest cracked version of Doom or whatever is popular this week. This function will be especially useful: http://php.net/getimagesize Once you have the file uploaded, you could scale it right away, once, and save the scaled version for use from then on. Or, you could scale the image each time, on the fly. The first option is more efficient. The second is more flexible if you want to change the image size later, or if you want to have thumbnails in one page, and full-size in another. (You can write one script to handle both) Your two main choices for scaling an image are: GD, which has to be installed with PHP (use http://php.net/phpinfo to check) ImageMagick (aka 'convert') which is a shell command you can install and use http://php.net/exec to execute. There are examples of using GD to scale images, and of using ImageMagick (aka convert) to scale images with exec all over the 'net, so I won't try and repeat them here. Oh yeah: Sooner or later, somebody will upload an image that's too SMALL. Don't try to scale it "up" -- That will be butt ugly. Just display it centered in the spot where the image belongs. Test this with a tiny image for yourself. Security Note: The directory where your uploaded images are stored should *NOT* be in your htdocs web tree. You can use PHP to make sure the image is kosher and *move* it after you check to the web tree. Or you can use PHP to check/read/display the image, so it's never in your web-tree. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
