So if i did this... Invert the psd, copy it, undo it, and go to the alpha chan i post the invert it should work?

You need to explain that better. But, all you need to do is use the Marquee tool and have it go around all the parts you want visible. Go to the Alpha channel and with the marquee tool still outlining the design, you need to grab the brush tool and fill the it with white..

I did it my own way, but thanks face for the general, invert idea :3
