I have used their content in past and must say that all their content needs re-compressing (or sometimes re-sizing) since I don't want to post images of 100k+. The absolute max. file size I'm using on my galleries is 75k, and for tgp galleries 50k (but then I try to keep the average size under 40k) - so I re-compress the original images and then run the gallery through ThumbsPlus' web-wizard =
resulting in same pixel sizes (~120 x 160 pixels) with file sizes between 3k and 5k - here's a
sample or their ready galleries (re-worked - only 108 x 140 thumbs) and of a
tgp gallery (with 120 x 160 thumbs)
