How do I add thumbnails to Community Content?

[Tamren Shade]

Dumb question, but I can't seem to find a clicky-thingy or texty-thingy to add thumbnails to the title line of my ships in community content. It'd be greatly appreciated if someone could explain to me where and what I'm obviously missing :P

Technomancy hard! Me no understand! Gonna find some rocks to bang together for fun and maybe club a sabertooth for the tribal supper tommorrow :P
