Okay, I've got a pretty much finished set of Portal textures, gathered from various mods posted here. I did not create any of these(apart from inverting for white backgrounds). All problems have been fixed with this version. I made the white ones jpegs instead of pngs before. Shows how much I know

Credits go to:
blue_h3x, for hit2 and tiles
iccy, for rings 2
BlackSash, for particles1 and 2
Me, for creating particles3 out of particles2(copy/paste/rename), hit1 out of hit2 and rings 1 out of rings 2
