These arent actually mislabeled, but changed the extension only so fof can see them. jpg format is, of course, supported in code but the implementation of the extension isn't. a lot of themes use jpg with the changed extension to save on space when it comes to images not using a transparent layer. Its been in the issue tracker for a LONG time, and in time it will get included to look for additional extensions so we can use them directly without havin to renam the extension to use them.
You misunderstand. Max just added support for JPEGs to be used natively. In the latest revision you can rename them to .jpg and they'll still work.
EDIT: And by latest revision, I do NOT mean 3.120 Final. Just to make that clear for anyone at home who goes to try this. (r1893 is where it's at)
