Calling javascript file with image tag

i dont know if its possible but i wrote a .js file and renamed it to test.jpg i called it by using the tag <script src=”test.jpg”> however nothing happened. when i renamed it to something else like test.111 it would work, so i was wondering if there is a way to call the javascript with the same img extension or even calling it by using the tag <img src=”test.jpg”> and running the javascript file.

I cannot show the contents of the javascript file and yet i still need to run it as an image file.

Thanks
