Devin linked to a free image manipulation called paint.net on his work blog (e)mail insecurity.
Well I discovered that I do not have photoshop on my computer like I thought I did. As I was helping clean up some pictures for my friend S I needed it. Since I remembered Devin talking about paint.net I went to the blog post and followed the series of links to find the download. Even with me needing to download the "whole" package which included the dot net framework that paint.net was installed on it only took a few minutes to download on our DSL line. It was installed and I was manipulating a picture under 5 minutes later.
So far I have not found anything I don't like. Being somewhat familiar with a variety of other photo manipulation software made this very familiar. In fact it was somewhat easier for me to use as I did not have all the menus and stuff to wade through. For the most part I do cropping and some light adjustment. Other than that I don't do a whole lot of photo manipulation. This time however I was cleaning up a baby picture that was about 50 years old. I had to clean up the black smudges and various white marks on it. It was a lot easier to use than I remember photoshop to be. I think I am very happy with the program and definitely suggest it to others who do not need a high end professional photo manipulation software.
To get paint.net go to http://www.getpaint.net/ and download the complete package with the .net framework unless of course you use .net framework already.
