Sorry if my explanation wasn't very clear.
Here's an example of in-image use of "Apply Image":
You're printing a red and white design on a black garment. Create
three channels named "spot red", "white", and "white base" - set the
opacity on each to around 70%. Go back to RGB channels and select red
parts of your image, select the spot red channel again and fill with
black. Repeat for white portions - add them to the white channel.
Now 'Image->Apply Image', select "spot red" as the source, "white
base" as the target, and "Multiply" as the blending mode. Repeat the
last step, but choose "white" as the source channel. Now you have
combined "white" and "spot red" to form a white base that you can then
choke down - and see the result on the screen before going to press by
hiding the RGB channels.
That's a pretty simple case - sometimes you want to subtract all of a
channel that overlaps another (blending mode "Add", "Invert" checked),
or selectively mix portions of channels.
The idea is similar to the Channel Mixer dialog in GIMP - but the
different blending modes makes it very powerful.
Does that make sense?
