Kevin, From the tool palette, select "Color keyed selection" and the "Exclude area" logical button. Select "Process/Standard adj/HSV Set". Set R, G, B and Var to zero. Click on "Key on RGB" for faster processing. Click on Done. Imagemaster will select all pixels which do _not_ fall inside the color range, i.e. everything except (0,0,0). The next requester asks what to do with those pixels: Hue should be off, Sat should be applied with a value of 0, and Lum should be applied with a value of 255. Click on Done. Presto! Imagemaster whitens everything that wasn't black. For a softer keying solution, check out the macro I'll be uploading in a few days. It creates antialiased alpha channels, so you'll lose that jaggy border when you superimpose those trees. Blaq!
