This doesn't happen if the extension is ".jpg," only ".jpeg." It also doesn't happen if the image is embedded in a web page -- only if I try to view the image alone.

That can happen if that image isn't send by the server as image/jpg because the server doesn't recognize the .jpeg file extension and sends it with a generic file type.

You can check the response headers via an extension like Live HTTP Headers.
