For 800x600 you can compress it to about 200k no problem without any loss of detail or resolution. Man I produce 1024x768 all the time and none of them breach 280k , and they look as sharp as I rendered them. If you go below 175k for 800x600 then you've gone too far because then the resolution starts to go and you get blurry blotchy crap. Oh one other thing not all programs use the same algorithm to compress. For instance my ACDSee3.0 will compress just fine but if I use anything else at the same compression ratio I won't get nearly as good of results. Bottom line , just experiment on ratios till you get the visual quality you want without torturing us analog dial-uppers with long download times for mere pictures. Late!
