I had the same issue with a Samsung SyncMaster 940bw monitor.
When displaying and viewing photos in Windows Photo Gallery of Vista, some monitors or LCD flat panel displays may have a strange problem in which the images will be shown with a orange or yellowish tinge in photos’ background, affecting the display natural color of pictures to become something like Sepia effect. The entire window on WPG appears to be colored in slightly yellowish tint, and is therefore appear darker, including the panels on either side of the photo display which which appear yellow on the desktop but are white in actual.The yellow tinted photos may also affect other default image viewer in Windows Vista
The first workaround is by removing any existing ICC or WCS color profiles that are been associated with all display devices or monitors. Else, you can also try to change the default color profile for your system’s monitor to sRGB IEC61966-2.1, simply by clicking on Add, and then select sRGB IEC61966-2.1 from the list of profiles installed on system. After adding, click Set as Default Profile button. Exit from all dialogs and reboot your computer, and the color problem on Windows Photo Gallery is fixed.
If your system doesn’t have sRGB IEC61966-2.1 profile under the ICC Profiles, you can download the color profile from Adobe. Unpack the zip file, the right click on each of the .icc files in the RGB Profiles and CMYK Profiles folders (or simply just the one you need to use) and click “Install Profile” on context menu to install the color profile to system.
The first workaround was the solution for my system 😀
