automating layer mask application?

[KrytenKoro]

I have a lot of pairs of images with (1) color image named with the form "img-####.png" and (1) layer mask named with the form "img-####.png". The layer masks are usually but not always adjacent in number to the color images, not sure if that helps.

I have 0 experience with writing macros, installing macros, or running macros, so I will need some help with that if you're willing.

What I need is one or two macros that do the following:

Layer mask image:

Select All
Copy
Close image


Color image:

Add layer mask
Paste layer mask
Overwrite image
Close image


Can someone help me with this?
