Yes it will tell you!  All you have to do is tell the jpeg compressor in 
the gimp's save as screen to use a preview window.  Its a click box.  Then 
you can see the image degradation in a second or so, and the output size as 
you adjust the compression slider.  I can generally take a 2.2 meg jpeg as 
it comes from my camera, and shrink it to 18-21% before the image falls 
apart too badly.  Someplace in the 120k size still looks pretty good.
