There are still one or two Windows computers out there on the web, and apparently their browsers just set the MIME type according to the file extension anyway.Can't you just open the files with some graphics application and see what it makes out of them?(If you use a Mac, Graphic Converter is by far the best program for this. It knows *all* graphics formats and with its built-in scripting features ought to be ideal for doing this work automatically.)Frank Nordberg http://www.musicaviva------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
