I don't know how they're called but I would like to implement one of them on my board. i'm talking about these banners that are in standard dimensions (eg. 480x60) but when you hover them they expand to a much larger image.
I'd like to put one of them in the upper right of my forum to advertise some events but I've tried to google with no luck.
Any suggestion on how to find the code and implement it in XF?
