HaloMods "Classic" Read-only Archive

I heard that Jasc Paint Shop Pro can read DDSs somehow... how? Where's the plugin if there is one?

It uses the exact same plugin as photoshop. just put it in the plugins folder.

Okay... that works. Yay. Now why the hell does it save all the images to where they are "merged images" apperently and are REALLY FREAKING WIDE. How do I stop this? It says a dialog box when I try to save saying:
"Due to the file format limitations(and possibly the save options you've selected) this will be converted into a merged image.
Do you wish to continue?"

Then this save option thing comes up that's too big for my monitor and I can't even see all of it(god that pisses me off) with all this crap on it. Is there one or something that fixes this?
EDIT: I don't mean all of a sudden the image comes up real huge, there's a option window that comes up which is too long for my monitor. Then, if I import it in the Halo Mapping Tools, it's too wide.

I have no idea, I only found that off google.

Nm, just gotta put it at half-size before I save it.
