I tried hunting with the search forum engine but found no luck with answering my question. I see phenomenal textures all over the forum, but I guess I'm alone in this, when I used HLMV to change the texture say for instance Dillinger's hand and sleeve textures...I always get texture wrong size. So I assume I need to change the texture size...anyone recommend any program to do that, or any advice at all would be fantastic.

I personally use paintshop pro for resizing stuff, but programs like photoshop will work just as fine as well.

you dont necessarily have to resize anything all u need to do is decompile the model, save over the old texture and recompile and wallah! there u go:D...hope that helps
