Pete,
I use a Mac also, what is the application that was used to create the screensaver? I tried Powerpoint and Photoshop but neither recognize the file.
If you want to make this available to Mac users just create a file of the jpgs in the order you want them displayed and make that file available for download. Then we can plug it into our screensavers.
I use open source when ever possible. The application is called Xnview. I have created a zip file for Mac users.
Here is the link:
