I had better reduciton results with the png files than with the jpg files. Less blocky patterns when reduced. Also if you know what your finished desired size is then run the file through an external app like Photoshop for file size reduction. Rev is not that great at doing the reductions itself. I was able to have all of my png files at 75 % of screen shot size. I would say that png's are closer to bitmaps then jpgs. Tiff files of course being the best for image quality but with a much larger size. Jpg files have the broadest range of enlargement/reduction but with some garbage thrown into the image when in low files size mode. BMP files are the most accepted file format with less of a file size than tiffs but more than High jpgs.
All in all if I am doing high quality work where size is not a problem I use tif files. If I am doing just web based then I use jpg or pngs and sometimes gifs. If I am doing CD work than I use mostly png's but will use jpg's for smaller file sizes. For photo manipulation I only use tif files at 300 DPI and at least 200% of original size then after the retouch I then reduce either the DPI for non print jobs or the percentage for layout work etc. For Large CD project I will reduce both and convert to PNG or JPG.
In my cross platform tests I found that BMP, JPG, work in more applications (commercial and non-commercial products) with png and tiffs coming in a close second for most commercial applicaitons.
Just remember if printing is not an issue than 72 DPI is enough but if printing High quality then go to 300 DPI but if space is an issue than 150 DPI will definitely be enough. Lastly using the same color pallet will make screen redraws faster and is a must for any transitions.

Tom,
Thank you for the advice.
I have never worked with png files. I understand that they are like a "super
GIF", similar format, more colors. Do you know if pngs are bitmaps? I would
like a format that scales well.
So far, for everyone following this thread, the most important thing I've
learned is: keep the images full sized, if possible. Reducing the screenshots to
75% caused more problems than using any of the formats I've tried.
