Masking/Cutting/Layering?

[kristalyn]

How do I cut out an organic shape/selection from one image and then overlay image onto another image? Or how do I cut out an organic shape/selection from one image and then overlay onto another image?

I'm brand new to GIMP but have a little experience with Photoshop and have tried using masking, layers, and paint bucket with image as a pattern but can't quite figure it out. Many thanks in advance!

dumb question, can you give an example of "organic shape/selection"

On a basic level, if you have both images open "as-layers" you can trace a shape using the free select tool on one layer (image-1) then copy that selection from the other layer (image-2) and paste back into image-1

...but there are several ways in Gimp. It all depends on your example
