You cannot "inject JPG". JPEG is just a file format. - Nothing more.
If you are able to include in a PHP script you can also include JPEG files, but this is only reasonable if there is PHP code in it.

As I already said, JPEG is yet another binary file format. So you cannot simply inject PHP code in a JPEG and get the code executed.
But you can write your PHP code and save the file as *.jpg file. Then you can include it in another PHP script or get it parsed through command line PHP or .htaccess.

By the way... Yes, there was a vulnerability in the JPEG parser of Microsoft, if I remember right... But PHP? Forget about it.
