Outlook doesn't have settings of its own. It uses whatever you configured for Windows.
I am also having this issue on an XP machine.
Windows Explorer has the default program for JPG as windows picture and fax viewer. Outlook opens them up in Paint.
Just a quick question, but have you confirmed they are specifically .JPG or .JPEG files?
On my Win7 box, default programs has JPG files are Windows Live Photo Gallery, and Explorer and Outlook 2010 (Final) both open correctly.

I'm having the same problem with paint. It doesn't matter if it's JPG or JPEG files. Both are set in the Control Panel to open with my default picture viewer (ACDSee).
Even funnier is that some open in ACDSee. Other's open in Paint. I've tried to find some correlation, but can't.
This is REALLY frustrating.
I finally figured it out - If you have windows 7
Select the windows button (bottom left corner) to the right you will see deffault programs - click on that
Then select Associate a file or protocol with program
For myself my pdf's were opening with picture viewer - I found the extension .pdf and changed the program to adobe
Problem solved!

Another way to do this is:
1) Copy the file for which you want to change the default to your desktop. (You'll only have to do this one.)
2) Right click on the image
3) Select Properties (the last choice)
4) On General, you'll see "Opens With" Select the "Change" button
5) Select the program you want to use (popular ones will show up automatically, you may have to hunt for others)
6) Select "apply" and this will automatically set the property for all images/documents of that type.
7) Note this also works if you don't want Notepad to be the default for text files, etc.
8) Also note, as mentioned above, the .JPG and .JPEG are considered different file extensions so you'll have to do this once for each file type.
Hope this helps.
