Windows Picture & Fax Viewer--where does it select the pics to view?

Factual Questions
1

I just recieved an email from a friend with 10 jpgs attached.
In Outlook Express, I clicked on the icon (paper clip) for the attachments, got the list of pics, and clicked on one of them.
The picture opened in a new window, title bar “Windows Picture and Fax Viewer”.
At the bottom of the window there are arrows backwards and forwards, but these don’t take me to the next pic of my 10 jpg attachments.These arrows cycle through a bunch of files–mostly named .gif or occasionally jpg–which are mostly the icons or advertising pics from the borders of web pages.But not exclusively from web pages–some of the pics cycled through are jpgs that were sent to me as email attachments.

MY question is: from where does the Picture and Fax Viewer select its pictures?
I’m guessing that some of them are related to temporary internet files, but not all of them, becuase the Viewer also shows me pics from email attachments

For each one of the 10 pics my friend sent me in this email, the Pic&Fax Viewer opens the pic, then cycles through about 30 gifs and jpgs, and begins repeating itself. The 30 files shown are diferent for each of the 10 attachments.Some of them were from web pages that I had viewed under the “in private” mode of the browser (IE8). (and, sorry…they weren’t porn --it was worse!–the gif icons were from pages on medical issues that I would thought would remain private if I viewed them on the “in private” mode.
So my next question is : how do I control the Pic&Fax Viewer’s selection?

(I have a simple PC, using Windows XP Home Edition, installed legally)

It goes by the folder the current image is in. Apparenlty the attachments were saved in the same folders as your Internet cache, which is spread out in multiple folders for efficiency reasons.

If you were to save all the photos into a single folder, and then right click on one and choose preview, the program would work as you expect.

Stuff like this is common using older programs on older operating systems. They weren’t designed with the other in mind.
