In my opinion using image swap behaviors is counterproductive. It makes for slower loading pages and consumes bandwidth. This can be a problem for mobile device users who often pay for bandwidth usage.
I'm going to show a neat CSS trick for de-saturating color images. When you hover over the images, they turn to color and their opacity increases to 100%. Click on images to bring up the full size photos with captions.
