Addnl details on the problem:
When I opened other image files using Windows Photo Viewer, the same thing happens, they turn yellowish. So, it may be a problem with the Windows Photo Viewer, but how can I fix it?
The yellow tint is caused by a bad profile installed for your monitor. A lot of programs do not bother with color profiles but IE and the windows picture viewer do.
In your monitor prefs, remove the currently set color profile and that should fix it. (Or set to the default sRGB).
I'll have to wait till I'm home to print out the steps unfortuantely...
1. What do you mean by "bad profile installed for your monitor"? I didn't use any installation CDs or whatsoever for my monitor. The only installation CD I used that could be related to graphics, would be the installation of the Driver for my Graphics Card.
2. You mentioned that IE and the windows picture viewer uses the "color profile". The strange thing is that the preview thumbnails of the pictures appear in the correct colour tone in Windows Explorer but appears with a yellow tint in Windows Photo Viewer. In fact, the borders (encompassing the picture) provided by Windows Photo Viewer is yellow instead of the supposed whitish/greyish-blue.
How do I go to the "monitor prefs"? I don't see any option resembling "color profile" when I right click on the desktop and select "Screen Resolution":
Control Panel\Appearance and Personalization\Display\Screen Resolution
The thing is I recently reformatted my hard disk and reinstalled Windows 7 Pro (the 2nd time I'm installing it. The first time I ever installed Win 7 Pro, this yellow tint problem did not happen...
