For some working tasks it's not ideal to have a cursor in view (e.g., visual working memory tasks). I've added a bit of html code that you can implement yourself if you want to hide specific images, but it would necessitate you to make duplicates of every image you hide (i.e., one copy where you hide the cursor, and another where you don't). For this reason, it's a bit inelegant.
N.B.: For the code, there are two images called "IMAGE_TO_HIDE_CURSOR_FOR.png" and "ANOTHER_IMAGE_TO_HIDE_CURSOR_FOR.png".
