My pictures folder - pictures have patches blue discoloration?

[stumped]

Pretty much as the title says , my pictures have suddenly developed blue/purple patches of discoloration that gets more visible when I zoom? What is this?

I've included a pic I just saved from google images to demonstrate. Pretty much all of my pictures are like this.

The picture is to small to make anything out. I can't see any patches at all...

Sorry. Hadn't realised that came out so small. Okay here's another one where it's more noticable

did you try going to command prompt
and typeing chkdsk /f and waiting
for it to finish?

I think it's a little early for that

Right, this is very strange but as soon as someone clicked on that last picture my pictures folder popped up and all my pictures looked fine again.   

Sorry about that you'll probably think I'm crazy but my wife is a witness to those darn purple shadows!

That's ok 
Glad you sorted it
