After you change the thumbnail size in options you need to go back in and regenerate new thumbnails in all your galleries.
My problem is I set my thumbnails to be 128×128 and then refreshed all my pictures to this size. But now the thumbnails don’t fit on my album page properly. I’m using the compact style and the pictures are too big for the display box behind them(which seems to be a gif file so therefore can’t change sizes?)
So my question is how do I get proper size thumbnails for my album pages, but leave the thumbnails on the gallergy pages at 128×128?
