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.
Has anyone figured this out? I still have the problem. Outlook should be using whatever program Windows is set to open the file in, yet jpgs and jpegs open in MSPaint 99% of the time. I've even done the "Send a Frown" thing requesting contact, but get no reply. I'd urge everyone else here to to do the same thing.
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

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.
None of these solutions work with my Windows 10 (free upg from Win7). My case is I have all jpg/jpeg/png's open In MS Office 2010 Picture Manager. Set this up in Control Panel as I've done since WinXP. Dbl-click on any such image in Win10 File Explorer and it will open in Office 2010 PM just as it should. BUT ... when someone attaches a jpg image in an email which I receive in Outlook 2010 and I click on the attachment, Windows 10 asks me EVERY SINGLE TIME what application I want to open the image in, even for multiple attachments in the same email! (I even tried the Properties approach described by Monica above and the Properties clearly said that a jpg image opens with MS Office 2010.)
This is a Windows 10 issue, I am certain, since (a) I have never had this problem before I upgraded and (b) the discussions above clearly show it isn't a problem with Windows 8 (which I skipped) either.
Since both Outlook and the OS are Microsoft products, I sincerely believe this is MICROSOFT'S problem.
