Thanks to you both. Both worked great. My attempt is below. I was able to get all of the plugins, except the invert alpha plugin. It was just a mishmash of letters and not a dll file. I searched around and found that I could use curves+ to invert the alpha, and did that, but my mask did not cover the entire image, as shown below. Should it cover the entire image or is that the way it is supposed to look? Also, is there somewhere else I can get the invert alpha plugin, or is the way I did it suitable? Thanks for your help and your time.
