I am specifically interested in the uploading of image files at this point but all media would be useful. Currently I am checking the width and height of the uploaded image when it is put on my server and before it is uploaded it is bounced back if it does not have a .gif or .jpg extension. Do I need some sort of third party software to scan it? I run the platform MacOS 9 and use Webstar 4.0 with WebCat 3.0. Alisha Outridge Spec Simple, Inc.
