Hi linhol, welcome to the Sony Forums 
There have been isloated instances of this in the past on the Forums. It's usually a software conflict of some kind. If you are PC-savvy you might be able to run a de-bug routine to find and remove the problem file(s). It's often security or anti-virus software that's the culprit.
Often the best solution is to simply use a different image browser, like Windows Live – there are any number of alternative free and commercially available apps that would work.
Hope this is of some help.
Mick
