Is there a way to set a default thumbnail? For example, most users aren't the brightest bulb in the bunch, and I frequently get people posting incorrectly, or posting topics in the gallery forums... and what happens is that a broken "Red X" image is displayed in those posts on the gallery as well as on the ForumHome page. I'm wondering if there's a way to detect improperly posted / no image topics and replace the thumbnail with a default graphic?
