Sorry I wasn't able to help you.
According to Windows Help and Support, "For viewing pictures and faxes, the Windows Picture and Fax Viewer has been replaced by the new Windows Photo Gallery." So it seems that we Vista users have no choice in that department.
Also, I should have answered your question about how I
view JPEGs. Frankly, because I do a lot of graphics, I simply use my graphics software, so that doesn't help you. However ....
Did you know that you can use Windows Explorer or Internet Explorer to open individual JPEGS? Try it with Open With, and you'll see what I mean. Don't know why I didn't think of that before - probably because it was too simple.
Give it a try. You might need to change your page settings for printing, but I should think that would be fairly minor.
Please let me know what happens!
