Graffiti kill marks

Is there any graffiti badges packs, i'd make them myself but this is my first day trying to mod fps' and not sure if they can be created using photoshop, if somebody could explain to me how to use photoshop (did look for a guide, only found a shit one) it would be greatly appreciated, preferably a good pack,

btw if i do create one, ill up it on here

you try search?, here ill check.
/edit no nothing on search, yeh someone might want to take up the challenge of making one, i would probably use it

I can make the images fine, im pretty good on photoshop, but the problem is knowing wtf to do after that :L e.g formats n shit
