I made tifs out of some jpegs. I inserted them into powerpoint XP, where the upper part of the image was OK but the lower part was completely corrupted. Nice patterns though. When I converted the same jpegs to tifs in PS 6, powerpoint inserted them perfectly. Is this a known issue? Does CS have a problem w/ LZW tif compression? Anyone know what gives?

I don’t know what the problem is but I can tell you that saving as JPG is far more efficient for screenshows.

Bob’s right and if you NEED a transparency, use PNG – Powerpoint supports it.

Val – you seem to be right. TIFFs compressed using CS won’t open in PP. But as the guys say, TIFF is not the best format for presentations as they swell up the size of the presentation massively (seems about a factor of 10 compared to a level 6 JPEG) which can cause problems. The originals will also take up a lot of space on disk in comparison to level 6 JPEGS.

Having said that, if you compress the images within PP, it seems to really shrink the size back down by a factor of five so maybe it’s not as much of a nono after all. However, I’m not sure what effect that compressing within PP would have on image quality.

Thanks for your replies, I know tiffs aren’t the best for PP. They were small images that I saved as tifs mainly to get out of the vast clutter of jpegs in a particular folder and were small images anyway.

The surprise was that CS saved tiffs didn’t work and PS 6 tiffs did. Didn’t PS 7 have an issue with LZW compression not working? Does this happen with any other use of CS tiffs?

There were some problems with artifacts. That was corrected with the
7.0.1 patch.
