Fading is not specific to jQuery, you can create your own fade animation (you just have to kinda reinvent the wheel). Basically you set up an interval (setInterval()) during which you decrease and increase the opacity of the image sequentially. But of course, you could just add jQuery and use that one. After all, jQuery is just JavaScript, too.

Note, however, that with your current set-up you can only fade out and in subsequently, not simultaneously/seamlessly since you’re just changing one image’s source attribute value. You need to fade out the image, change the src value and then fade in again.
