In that case, you want to apply transparency that varies from left-to-right
or vice versa.

 o Take the face image

 o Zoom in (tap +) until it fits display (for convenience)

 o Make selection of a vertical line (1-pixel wide) in the image

 o (*) Change opacity value of the selection

 o Move to next vertical line, repeating (*) with a different opacity value

 o At the end, copy and paste image onto the background.

I hope the image you are dealing with is small enough to make this
practical. If it is large, come back and I'll come up with something more
sophisticated. *smile*

Hope it helps,


PS - In that site banner, are you holding a lightsabre by any chance? I
suspect it may not help business, unless you are in showbiz.
