Someone made a plugin for it. See post update. Alright, no need for a tutorial. Someone made a plugin for it. See post update.

I've privately emailed you the solution. I'll probably do a tutorial based on it... once I find the motivation to do it... David, I believe I found a way to do it.

I still don't see any rounded corners, but the black lines (which is all the lines) in the original image are now blue. Just so I understand what I'm trying to do, have we just drawn rounded corners on a rectangular image or have we created a new rounded corner image. If I understand an image size is defined by its length and width, so its not possible to define anything but a rectangle.

Was that done? Make sure to select the layer before changing the properties (changing the blending mode). This ensures you are editing the layer, and not the original background. If your picture is on a white background, could it be that the rounded corners aren't so obvious? What happens is that a 2nd layer is created, with a black rounded rectangle on white. Because the blending mode on this layer is "Additive", it "adds" the RGB values onto the 1st layer. Since black is (0,0,0), nothing is added onto the 1st layer for the black rounded rectangle. The white part will basically make the corresponding part in the 1st layer white. So in the end, you get the original picture with rounded corners.

At the end when I "Check the background layer back (to make it visible again)". I get my original picture with the sharp corners. My picture is a graphics design on a white background. Any ideas?
