HELP! IM AM SO SORRY.

god. i'm so sorry to post AGAIN.
ahh! i'm just under a lot of
pressure to make icons for people.
ok:
texture tools? right?
im guessing that's what they're called?
look like this:
&
and whatnot.

well, i look at all the tutorials and see these but for a while couldn't figure out what they were. I thought it was the same thing as a paintbrush! & became frustrated when i wouldn't get the same effect. But i realize now, this tool & the paint brushes that i load are totally different, and have totally different effects, correct? So here's the big question:
where do i get these things [textures] for PhotoShop 8.0??? Where can i download some? Because I try to download some & i end up only getting the "baseset" or whatever, you know where you only download the jpeg images of what the textures actually look like. I can never actually get the file to put them into my PS. And lastly how do i download them into my PS. 8.0??

i know this post is JAM PACKED and im truly sorry.
but ANY help would be so appreciated!
Maybe you could even give me a website / tutorial
that already answers this so you don't have to?
THANKS SO MUCH! I LOVE YOU ALL FOR YOUR GENEROUSITY! :]
