White parts become black. might be transparent, too. Not sure.

Maybe you could have checked before posting to help us help you?
Have you tried settimg the background to white?
Without some script code there isn't much we can help with.

So you seriously think we create a function to display a JPG in a gui and then deliberately  fuck it up by making a part black?

haha obviously... Back in school when we programmed in "MetaCard", there was always one color in a jpg assigned to transparency,
so I assumed this might work in the same way.

It seems to be the white parts that are discolored, mirroring the JPG compression there I guess.
I use GuiCtrlCreatePic.

I just tried to change the BkColor and sure enough, its transparent!

Use GDI+. There are plenty of examples how to display an image in the GUI properly.
