In the last couple of months a lot of my pictures are experiencing a very strange disease: especially in dark areas a lot of pixels are getting replaced with white spots - see for example: http://www.pbase.com/image/22753200

Strange enough - these wrong pixels have not been there when I first uploaded them - and I have never reposted since. I've seen other users experience the same problem on pbase. and even stranger: if I download an "infected" pic and open it on my computer it just looks fine again!
CAN ANYONE HELP???
Thanks a lot!
