I decided to make some quick-n’-dirty desktop images from today’s big Mars photo. I use two monitors, so there’s a 2560×1024 version there too.
Some people prefer a big sky, others like lots of land. Take your pick. It’s the photographic “rule of thirds” in action!

2560×1024 | 1600×1200 | 1280×1024 (Windows)
1152×768 (Mac)
It looks like the original photo is a pieced-together composite of several other photos. I didn’t really feel like fixing the stitching, so there you go.
