Hi,
some eeks ago i had the idea that a very small thumbnail could have a much lower quality than a 800x600 "final view" image. That saves badwith on overviewpages with lots of small thumbs. If you want to have your "final view" big images in good quality, then you set quality to 100%, but then all thumbs (that also look ok with 50%) would have 100% too.
Is there a way to have the thumbnails with 50% quality and big images with 100%?
I even tought about cioding but some skilled people told me that coding that would be a very hard task.

How many thumbnail images do
How many thumbnail images do you think you will have, both per-page and on the entire site?
Honestly, changing the JPEG quality on a small image, like a thumbnail, doesn't have nearly the same savings as changing it on a large image.
Unless you are hosting thousands of images, and expecting thousands of requests, I wouldn't worry about it too much.
However, 100% quality does take an inordinate amount space. In small-scale situations, I have set the global image quality to 95%. That has a drastic effect on total bandwidth with an almost imperceptible change in image quality.

yes, for thousands of thumbnails and other images. At the moment around 7200. At the end of the year there will be 10.000. Thats why i think about that.
