LÖVE

So I'm working on and overhead zombie type game but I'm not very gifted at art design so I need to download some sprites and background graphics for the game, preferably free ones. I'm wondering if anyone know's were to get some good ones from. I tried google searching but didn't have much luck as I didn't know were to look. I'll work with just about anything so long as it works with my theme I just need some period though. Can anyone help me?

Wow i kinda feel like an idiot for not looking more closely on the wiki thank you
