**Promises** are almost always better than callbacks, so can someone replace almost all callbacks with Promises.

Adding promises would actually shorten the functions by removing the error, and success callbacks, converting `loadImage('test.png', success, err)` to `loadImage('test.png')`

**ALSO,** I feel like that should keep the `whileLoading` callbacks, or any other repeated callback since those are needed and may not even work for promises! _(It would be really cool if you could send values while a promise was pending, so you could send the percentage that a file has loaded in before it was finished or something. like that… )_
