Surround SCM: Image Comparison/Diff

Surround SCM
I've been a member of the Surround SCM team for nearly a year and half (including my co-op) and there are still little features of Surround SCM I've never used or wasn't aware of. Just this morning I was looking into a defect about the "Image Comparison" tool and it hit me - up until that point I had no idea Surround even had an image diff feature. So I started playing around with it and, as it turns out, it's a nice little tool. I imagine it would be quite handy if you were a graphic designer or someone who spent a decent amount of time working with images. To launch the "Image Comparison" tool open up the Surround SCM GUI client and select an image file from a source view window. Now right-click (command-click on Mac) and select "Differences" (you can also select "Differences" from the Activities menu). After the dialog opens click the "Advanced >>" button. You now have the option to perform an Image Comparison on any file on your local computer, the selected image on a different branch, or any historical version of the image. Make your selection and click "Differences". Alternatively, if you plan to perform a historical comparison, you can select two different versions from the history dialog and click the differences button on the right hand side. You have four options for view an image comparison, "side-by-side", "top-over-bottom", "combined difference" and "high-contrast combined difference". Following are some screenshots. Happy diffing!
