Scrolling Thumbnails
 

Not sure if this can be done or not but with so many uploads happening often I thought it would be kind of neat to have the random images on the forum home act like a marquee. That way you can display more random images with out having them get too tight.

Again I have no idea if this is even possible and what it would do to the forum in general ( if it'll slow it right down or not ) But I thought I would mention it any how. Wish I knew how to code, cause I would do it myself but oh well :p

Not sure if scrolling images will get added, but you might be able to find a free JavaScript option via Google that you could use to scroll images.
