Thumbnails of all pictures are blurry. Help!

[Mitch444]

I'm not sure what is happening on my computer (27 inch iMac running 10.6.7), but I need help.

Over the last week or so all of my image thumbnails in the folder come up VERY blurry. Even if I use the "cover flow" viewing option I can only see huge pixels. This was not a problem before.

Any ideas on how I can get my thumbnails back to normal?

What folder? Is it possible you're looking in the Thumbnails folders that are created by iPhoto?

I know that may sound like a stupid question, but it's not meant to be insulting, btw. Sometimes it's the simple things that get us hung up.

It is happening on the desktop and in a few folders that I have images in. it is only the .jpg files that appear blurry. I have also edited these photos in photoshop.
