I have a group of high-resolution images I've uploaded to my gallery, but the thumbnail images are of unusually poor quality.
I've tried changing the thumbnail sizes. I've tried checking and un-checking the "fix dimension" box. I've tried changing the thumbnail using the "edit thumb" feature under the Gallery Manager. In each of these cases, I've made sure to regenerate the thumbnails, but nothing is working.
Anyone else having this problem or know of a solution?
