Custom textures/weapons and sprites?

[SayWhatOneMoreTime]

Is there any site I can get custom weapon sprites from? like a grenade and a singleshot shotgun? and can I use ms paint to make custom textures?

And is there any civilian sprites that run around? and some that sit? I'm trying to make a city WAD with civilians you have to capture and save/kill.

If anyone knows where I can find these things thanks in advance!

ZDoom spriting carnival thread will help you. But don't forget to ask author of the sprite-set before putting it into your mod.

@Gifty Is there a search engine on realm667? because I can't find what I'm looking for.
