How do you make custom icons NOT show up black ingame?

Okay so I'm sure this has been explained before, but if somebody could give me a quick explanation, or point me to a tutorial that'd be great cause every custom icon I Try to make always comes out as just a black square ingame.

I have photoshoip and an image converter program, so what am I doing wrong? Is it the way I'm saving the .tga file before I covert it to .blp? IS there some setting you need to make for it to work right that I don't know about.

the loading screen thang coulda been easy but no blizzard had to make it as confusing as possible..

EVERY picture in war3 (icone, skin, screen...) needs an alpha channel.

And if you don't know how to add an alpha channel go here.

for me it didnt show up with just an alpha i had to copy the pick in regular form and and paste the copy in the alpha channal (sry if thats common nolege) (and forgive me of my unholy spelling)
