can't set Firefox as default JPEG viewer

When I double-click on a local JPEG file, I want it to load into Firefox. However, when I try to "Choose default program", Firefox isn't listed as an option. I can browse to firefox.exe in the dialog box, but doing so doesn't select it or add it to the list of options. Why is this? How can I force Windows to use Firefox as the default viewer?

Ok, I tried that and, for the record, it did nothing to fix my problem. Here's what did fix it: I did some digging through the registry, along with a lot of Googling, and found the entry that was causing the problem -

[HKEY_CLASSES_ROOT\Applications\firefox.exe\shell\open\command]

@="\"C:\\{the path to an old (and since uninstalled) version of}\\firefox.exe\" \"%1\""

It seems that many of these newer Windows features can't handle it when you try to keep more than one version of a program installed - or even if you install two unrelated programs that happen to have the same executable name. Once I pointed this entry to my current installation of Firefox, everything started working the way it should - although I shudder to think how confused it'd get if I were to install two different programs both called "example.exe". However, even though this is more of a Windows problem, you would think the Firefox installer would know to look for and correct errors like this.
