Photo Gallery Problem (RTM)

Hi everyone.
While viewing photos or pictures in Photo Gallery I have a strange yellow
background - this background changed to yelow suddenly... but it's not all -
all pictures I open with Photo Gallery look as if some yellow color filter
has been applyed to them.
I posted a question in my local Discussion Forum and no useful answers BUT:
one person said he had the same problem but the background is light-green,
the second one told me he had Pink background and the third one said he had
the same yellow background as me. In all cases there's not only strange
background changing butn there's color filters applyed to pictures being
viewed (the filter "tone" is the same as the backgroung).

Please help
