Omg this is so awesome :3 Imagine a Skyrim themed banner *-* with dragons and ****... or maybe one with Amumu because Amumu is super cute! Orrrrr or or or or A Hipster themed banner... BAM
As much as this would be great imagine how hard it would be to monitor/ police for appropriate pics. Though a catalogue of usable images would be a nice way to avoid inappropriate content.
Kan. This is absolutely awesome. I wonder if you can make an Aviation themed banner for an old friend? Guess you won't though...
