Perhaps I should clarify some things about image sizes. Some now work correctly. I do get a few that are full-screen, and get the magnifying glass cursor that allows me to expand to full size - outside of screen dimensions. That has changed in the last few days.
Many tables of thumbs are, however, are less than 3x3, and are not live.
As for individual images, I have no way of knowing what the size is supposed to be. In some cases they are full screen in one dimension, usually height. Others are 6 or so inches on a side. Many are, however, around 2 or 3 inches high/wide. That may be the poster's choice, I have no way of telling.
In any case, when the new SW was initiated here, what always had worked OK before changed a
LOT. I also have
NO issues on any other sites I visit - same as always.
And, where I do see an image size on the Window ID, it is what I actually see. For example, on this one:
http://www.gayheaven.org/t19236-dm-jason-white-fucks-aaron.html, the Window says 189x140 pixels, which is about the typical tiny size of many panes of thumbs I see.
