GitHub is all about comparing versions right? So why not make comparing images more awesome? GitHub now has view modes for image diffs.
- Two Up: Lets you see your versions side by side, and shows you any changes in image dimensions.
- Swipe: Allows you to see edge to edge changes making it easy to detect minute color shifts.
- Onion Skin: Allows you to see through your versions, making subtle alignment shifts easier to spot.
- Difference: Lets you quickly see which pixels in a image have changed between versions.
