Could we have a ?height=xxx&width=xxx in the image URL? This way, I'll be able to resize it to 90x45 pixels (or something similar), and use the image on a particular forum (which only allows 90x90px max image signatures).
I'd love a custom size that then filled with as many site icons as fit... just because :D Do it high and wide and all of them fit... leads me to another issue I'll just log.
