simple

document.getElementById("bg_image_set").src='your image source';

will change do the trick. but what do you mean in particular folder? if particular means users local folder that you choose not user, then in javascript you wont get benefit. cause most user disable those option. but if you mean in your server then you will have to ask the question again, but if you mean user can chose where to save then you will have to do the trick with header
