Those "Rotate..." items are put there by Windows Photo Viewer. If you only see them with jpg files, I guess you are using another image viewer that has taken the associations for everything but jpg? You might try to add jpg to that other photo viewer's associations.
Otherwise, a quick fix is to disable Windows Photo Viewer. Navigate to:
C:\Program Files\Windows Photo Viewer\PhotoViewer.dll
Take ownership and full control of PhotoViewer.dll
Rename to PhotoViewer.dll.bak
You might like an alternate image viewer - how about FastStone Image Viewer

I recommend using the portable version.
In the settings interface, associate all your image files with FastStone and everything will open with it, and no context menu "Rotate.."
P.S. I did look for a registry or a dll-hack fix, but it is not readily apparent - maybe buried in binary code somewhere ...
