I'm doing up some slides on Mac OS/X, using Office 2004. I'm including some window grabs from Grab.app, and for many of the slides, instead of the picture, I see "QuickTime™ and a TIFF (LZW) decompressor are needed to see this picture."
Nice. The 'Compatibility Report' for reading this file back to Office 2003 on windows says that it's just fine, thank you very much.
However, some of the images did work, and the ones that worked were the ones that I'd edited before pasting into PowerPoint, either in PowerPoint itself or in Photoshop Elements.
So, if you've got access to both platforms and need to fix this, the easiest way to fix it is to go through each image on the mac, and use the redeye remover or scratch remover tool inside Powerpoint to force the image to be converted to something usable on Win32.
