Comment (by summoner):

 Hello guys, have to confess it is not 100% clear for me whether you are
 planning to implement a slider or some UX component to let the users
 change the default 80%. In some cases image quality is simply vital even
 if it consumes more bandwith.

 Furthermore once i had a site to sell goods. Images were generated with
 GD2 at the beginning. In case of normal-sized images it was good enough
 but below 200px the generated images tended to loose on sharpness. A lot.
 That was why i changed to imagick. Have to admit i used 95% quality but
 even the tiniest thumbnail was cristal clear that way. Even so filesizes
 were smaller than that of GD2-generated thumbs.

 So all i want to point on that thumbnail image sizes might be a bit more
 tricky as normal sized images, and you can not spare much bandwith on
 thumbnails. That is why i think maybe you could set a higher default
 quality for images that are smaller than 200px or so.
