Hi, it sounds like it's a limitation she's coded into her site, it's not a limitation of PHP. So what she's saying is if your file name is "yourfile.jpg" the part before the period is saved in the database and her script just adds .jpg to it, so if you have "yourfile.gif" her script will pull "yourfile" from the database and add ".jpg" to the end of it and that file doesn't exist since it's yourfile.gif... Hope that made sense.

Embedding Flash in a webpage is a little more complex than putting an image on there so having a PHP script that can do both images and Flash would be kind of complex.
