Help Windows fax tries to send images from temp folder

I recently was delighted to realize that Windows XP has a free fax utility and have set it up. I have been paying $10 a month temporarily to an online fax service, but that can't continue.

When I print a document to the Windows fax, it works, but only takes the first page and insists on sending extra images from my communications temp folder (which includes random images from emails sent in or out over the last year). It doesn't take all of them, just a few, but you can't choose which files to send, and if you delete the offending files, they're replaced by others from the temp folder. If I want to send a tax document to my accountant I could end up sending a picture of Aunt May and a copy of my letter to a friend as well. Aarg.

I tried deleting all the images from the temp folder, and was able to send out a clean test page to a friend, but new images are created in the temp folder every time I fax or receive or send images via email. I cannot be cleaning out the temp file every time I need to send a fax. And, well, it's confusing because even when I'm sending cleanly, the fax preview gives me at least one if not two extra images of the same page that don't send, because they are now created in the temp folder, too. It's unnerving to not know exactly what's actually being faxed out.

I'm running Windows XP Ultimate on a fairly new machine with Intel Core 2 QX9650, 3Ghz, 4G memory. I'm running relatively banal programs like Microsoft Office, Adobe desktop publishing suite programs, Real Player, Windows player. My phone line is hooked through my surge suppressor to my computer and appears to work fine for that one test page after the temp file clean out. I've googled this topic, but seems like I'm the only one, or I'm not using the right words. Any ideas or setting that's buried somewhere?

Or, if there isn't a fix, if anyone knows of a good fax program that's either free or is simple (ie isn't massive and come with a lot of other add-ons or things trying to "phone home") and doesn't cost much, I'd be interested.
