Running MBP with 10.6.8. I often want to open JPG files in iPhoto, but I want the default opening app to be Preview.

But when I highlight JPG files in Finder and right click on them, I get a list of apps that doesn't include iPhoto. I have to go to "other" and find it in there. A minor issue, but one I'd quite like to resolve.

How can I get iPhoto to appear in the list of available apps to open a JPG file? I have the Default Apps utility loaded, but it doesn't appear to cover this situation.
