Well, none of this worked :)
AngelDaniel and Neilo: I had created a 4th channel, photoshop itself names it Alpha. I can save it as a BMP with Alpha, just not a PNG (More on this later)
GfK: That does work, but then i cant work the alpha channel in an easy way: I have to redraw my image with transparancy (lets say i have a line, i have to delete current line and redraw a line using % transparency). I want to be able to edit my alpha channel, save, look at how it affects in game, re-edit etc..
JoeGR: You helped me out alot, i found out i cant do this thanks to you :). from the normal save dialog, it offers me PNG. From the web dialog, it shows : PNG 8, PNG 24. So ya, PNG in photoshop is RGB only not RGBA.
So....
I have to use The Gimp. Anyone know how to copy the alpha channel from one picture to another picture?
