This seems to be a pretty common problem in Windows Vista, related to invalid/corrupt color profiles – if you’re experiencing this issue, you’ll see a beige color bleeding through the image from the background where a white background should be. Here’s an example (thanks to matthewrowan.spaces.live.com!):
And, what it should look like:
Luckily, there is a fix (again, via matthewrowan.spaces.live.com):
After a little searching for how to change the background color, I found other people with this symptom describing it as an off color, yellow tint, orange or yellowish tinge, beige, cream colored background which, shows through the picture itself, distorts the colours, or bleeds through pictures. In most situations the problem went away in slide show mode. This was an annoying issue, making me avoid looking at pictures whatsoever in Windows Photo Gallery. This wasn’t that much of an issue because I do not use photos or pictures often on my development machine. But before I was going to install Vista on my other computer where I view photos constantly, I needed to ensure that I would not have this issue.
