ability to have a callback function to upload an image

[srchulo]

It would be great if there was a way to have a callback function that could handle uploading the images instead of just a URL to post to. This way you could handle custom upload scenarios, like uploading to S3, where you can't just give a url to post to.

you could create a custom API and expose that endpoint just fo that I guess.
