Once upon a time, when I used to look through "My Documents," for a photo file, a jpegs or gif file, I would see a little thumbnail of the picture as I was looking through the files. It made it much easier to scan for an image I remember, that I may not have remembered the filename for. That would happen if I were moving or copying image files -- a tiny thumbnail of the image would appear within the file management program so I would know what it was I was moving or copying or deleting.
Somehow, a few months ago, the preview capability stopped working. I now see photo files as these generic icons -- a sailboat going into the sunset on a white page, representing every photo. I have to open each file to see what it's a picture of.
What happened? How do I get back the preview capability that I once had? Could this be an unintended consequence of loading Picasa, and maybe accidentally making it my default photo viewing software? Is there any way to figure out what I've done and get it back?
If you can't already tell from my imprecise lingo, I'm not highly adept at this stuff. Don't be afraid to talk to me like I'm a 5 year old.
