Need some Photoshop Help

[lava]

Hello,
I'm on photoshop 7, and I'm trying to do something like this
http://www.mk12.com/

So far, I've created a layer with blotches of color and I've applied some filters. My guess is that I should add a layer mask to this and I'll have a colorized picture. I have an inverted grayscale image that I would like to use as the mask for it, but I don't know how to paste that into the mask layer. Whenever I paste it goes into a new layer (and I've tried paste into) Any ideas?

off topic: finally a change in footer & av I see, and youv chose the classic right hand side :thumb::D

I'm the one who first did the right align, way back in the day. telekinesis and I got into an argument about it, cause I wasn't conforming :)

so how did you end up doing it? please tell!

div tags. i think that's what i use.. or mayber it's just [align=right], can't be bothered to look.

I think last year my footer (centered, and flash, back in the old days) screwed up the forums a bit...

not that hahahaha the problem lava was having with his picture that he was asking about.

oh, apparently if you alt-click the mask, you can paste things easily. What I came up with didn't come out that cool though. I really want to learn how to do that kind of composition. It's tough. Is there a place for advanced photoshop tutorials like that? I want to learn composition, not how to make a gel button
