Yeah, maybe I'll just do that. I'm alowing users to paste images into a rich-text editor, so I'm pretty much looking at .png, .gif, or .jpg. Those should be pretty easy to distinguish by looking at the first few bytes. Pasting images may sound weird, but I'm using a jquery widget called cleditor that takes image data from the clipboard and replaces it with inline base64 data. The html from the editor ends up as an email, and the inline images cause the emails to be tossed in the spam folder for most people. So I'm parsing the emails, storing the image data, and replacing the inline images with an img tag that points to a web2py app that takes arguments that tell it which image to pull from the database. Now that I think of it, I could use php to detect the image type, and store that in the database. Not quite as clean, but that would work. Tobiah -- http://mail.python.org/mailman/listinfo/python-list
