Once the May challenge is done, I think we should move this thread into the Software Discussion forum. There are already lots of good tips and utilities that it would be handy to have there. Or maybe it should just be appended to the end of the Image Export Formats thread.

Some good advice from RobA:
The trick here is that jpg compression is designed for photos (or photorealistic images).
It is horrible for diagrams. You would probably get a better reproduction with a 2 bit gif on the diagram you posted.

You are correct. The shorter .jpg extension was made necessary because MS-DOS and early editions of Windows had a three-character limit on extensions. .tif and .tiff are also interchangeable for the same reason.
Since small file sizes in PNG depend on the number of colors used, those using that form of compression may want to review the color scheme generators linked here: http://www.cartographersguild.com/showthread.php?t=567
Reducing your image to a few colors can greatly improve compressibility, but it makes choosing the right colors more important. Those of us who are stronger technicians than artists can use some help with that.

Nice links except that as I read the first line it was wrong ! A JPEG is usually 24 bit but you can also do a greyscale JPG too. Thats a single channel version. That would sound like it would be 1/3 size but usually its nowhere near as small as that but it is smaller than a color one by maybe 20%.
