hmm.. here's an idea.. For those on Windows XP
Start -> All Programs -> Accessories -> PAINT
Yes, the stock standard boring Paint program with comes standard with Windows. Drops those screenshots from 2,305 KB all the way down to 132 KB when you save them as .jpg
sure, you can't adjust what size/quality %/scale with Paint.. but it does a damned fine job of converting huge .bmp files down to small and managable .jpg files... and it's free and you don't need to go and d/l any program from some website that might be full of viruses, spyware, trojans, malware, etc or might have this ugly "please support us and pay!" popup when you run it
