SOS JPG troubble in Powerpoint 2003 Presentation running in a Mac with PowerPoint 2004

[principessa_morti]

Hello.

Im trying to see on a Mac OSX PowerBook G4 (with office 2004 installed)
a PowerPoint presentation that was made on PowerPoint2003 (in a PC).

Some JPG images into this presentation (thats see perfect in the Pc
presentation ) appears like a black rectangle instead of the JPG
original images when the presentation run in the MAC.

I cant explain myself it, because these jpg are common...

well, the only particularity is that these files were made with adobe
photoshop.

Somebody may help me?

Thanks a lot.
