Jpegs made in CS3 (mac) not opening on Windows XP machines

Question

a few of my users have told me of problems that when they create a jpeg in Photoshop CS3 (with all the updates done) sometimes windows machines can't open the document. They open fine on other macs, just not on the XP machines. Isn't a jpeg a jpeg? is there some mythical setting that I'm missing here? Any and all help is MUCH appreciated.

Answer 1

There was a similar problem that popped up here at the place where I work... I run the only Mac systems in a company that has nothing but PC's everywhere else in the building...they run XP. Suddenly, for no apparent reason, the PCs would not display graphic files that were sent from my Mac via email. All of the PCs could display the graphics before, but now they suddenly could not.
It was discovered that Microsoft had sent out a service pack update that had included some code that "inadvertently" turned off the ability of Internet Explorer to view graphic files sent from Macs.
The fix was for the PC users to do some sort of setting to reverse what the service pack had done. Once that was done, the XP machines could once again view graphics sent from my Macs.
The IT department said that MS had sent out a fix, and they had to "back off of the fix" to reverse whatever had been done.
