I don't want to nitpick, but my smart doc on JPEG says: Quote: "Except for experimental purposes, never go above about Q 95 (i.e. 95% quality); using Q 100 will produce a file two or three times as large as Q 95, but of hardly any better quality. Q 100 is a mathematical limit rather than a useful setting. If you see a file made with Q 100, it's a pretty sure sign that the maker didn't know what he/she was doing." End of quote. The above statistics show 3 saves of the same picture with the JPEG 6.0 library. As you can see, 100% quality = 1:6 compression = 658.3 KB filesize 95% quality = 1:10 compression = 364.3 KB filesize 80% quality = 1:21 compression = 187.8 KB filesize. 100% JPEG quality doesn't mean a lossless save. There is always a big difference (in quality and filesize) between a PICT or TIFF save, and a JPEG or GIF save. But there is no visible difference between a 100% and a 95% quality JPEG save. Of course, the filesize or file format don't affect the memory load when the picture is opened. Different programs use different JPEG quality scales. For example, the QuickTime JPEG library saves the same picture with 100% = 1:9 = 420.9 KB 95% = 1:9 = 406.4 KB 80% = 1:11 = 331.8 KB.
