check for valid image types

[skyros]

Hi everyone,
Ijust finished a script here at work and am setting up some error handling when I ran into a snag. Im trying to find out if there is an easy way to check that a list of files are valid images? Right now, if someone tries to import a text file the script stops working but no error is given.

Suggestions?

One way is to check the extension against an array of know image extensions. I would say that would take care of 99% of the cases. Otherwise on mac you could check the file type but I would proably just trust the extension.
