One way to use the mask in PS is via the Select>Load Selection … menu command, and specify your alpha channel.
Make sure your image is positioned as a layer on top of a background image, then use Layer>Add Layer Mask>Reveal Selection to use your original alpha channel as a layer mask. Your image will show only in the areas where your alpha mask was nonzero.

I posted this in corels knockout NG, but they only get about three posts a month!
Help!
I have saved my knockout as an image mask. I want to put this mask onto a background. Following the instructions in the PDF manual I opened both the mask and my background file. I followed all the instructions on page 70 of the manual for applying the mask in Photoshop. It just doesn’t work! all I get is the cutout area of my mask surrounded by red. The background image shows through the transparent area of the mask. Can someone please help me with this? Paul
