High Res?

Can somebody explain to me how to get skin tga's to high resolution in Photoshop 7. Cause if I zoom in twice I'm working with giant pixels. It's probably something obvious I missed, but I've been looking for two days now. so some-one help me out please.

I thought it was image and then image size.

Remember that the skins can only be 256*256, 512*512 and 1024*1024.

Oh, and higher (I think). Not sure though :S

It's scaling up the skin to something huge, doing all your work, and then scaling it back down. It is a lot more detailed than when you skin the skin regularly at regular size.

At least thats what I heard.

It works thank you both.
