photos change colour before your eyes

[Smokeyone]

I have just opened a picture folder that I have not used for a couple of years and some of the pictures are either tinted green or yellow or have a green band covering the bottom half. After fiddling around I found out that if you open the folder quickly you can actually see the bands appearing on the pictures as you watch. Has anyone any thoughts please...
Thanks

I imagine it's all down to the speed of your computer and the Thumbs file being rebuilt.

I think you've inadvertently toggled the 'hallucinogenic' button on.

No I have not had "one too many" that's the problem - same pc hard drive and touch wood no other pix folder affected. Just the one folder that I have not used for ages...

Could it really be my pc speed......
