Hadn't really explored the differences between JPG and GIF. I figured the files were so small, that file size wouldn't be much difference.. boy was I wrong. This is an updated copy that uses JPEG compression instead of GIF. If you've already install this hack, just replace the files, use a SQL tool to "DELETE FROM thumb" and rerun admin/gallerymakethumbs.php.
In the future I may make thumbnail type a config option, but when I saw 20k thumbnails go to 3-5k, I decided quality was a mute point.
The main change is this line in functions.php:
PHP Code:
system("$galleryconvert -geometry '160x120>' $path GIF:$thumbname");
to
PHP Code:
system("$galleryconvert -geometry '160x120>' $path -quality '75' JPEG:$thumbname");
