Adding a specific type of layer
Hello, I am using an image of a frame as a base layer and adding a second layer containing an actual image so that I can put various images into the frame to make it look like an actual framed image. My problem is in trying to add a 3rd layer that would contain an adjustable white mat. When I simply add an image to the frame, it leaves an unsightly line around the image, I want to cover that up so that it looks like a normal image that's been matted and framed. The inner edge (cutout area) would need to be adjustable because the images I'm using can vary slightly in size and the mat layer would need to be adjusted to fit each particular image.
Any help is greatly appreciated, thanks in advance!
