Let me make sure that I understand the problem:
Picture files (like .jpg, .gif, .png, etc.) that are located in your My Documents folder give y9ou a "Not a Valid Win32 Application" when you double click on them.
Is that right?
If so, is it only pictures that are in the My Documents folder? Try copying a picture to you desktop (or, better yet, a flash drive or floppy disk) and try to open it.
My spidey-sense tells me that it's probably a system-wide problem, so I'm going to assume (for the moment) that copying a picture like I described gives the same result.
So, try this:
Open My Documents, right-click on a picture file, then:
- Point to Open With, and then click Choose Program.
- Notice that the Open With dialog box appears.
- In the Programs list, find Internet Explorer, select it
- Make sure that the Always use the selected program to open this kind of file option is not checked (see picture)and then click OK
If the picture opens correctly, then the problem is that Windows is trying to use a file that is not an application to open your images. This is easily fixed.
Post you results and we'll go from there.
