Modify Image Alpha

This is a Blender Add-on that modifies the alpha data of a Source Image based on the data from an image mask.

Both images MUST be PNG files of the same size.
The Alpha Image must be either a greyscale image or an image with alpha data to transfer to the Source Image.
There is a checkbox to indicate where to take the alpha data from.
Check the box to trnasfer the alpha data to the Source Image.
Uncheck the box to use a greyscale mask as the alpha data to transfer to the Source Image. By default it is left unchecked.
