Okay, thanks.
I'm trying to download dropbox paper file via files/export API, but arrived html is broken with images.
Only 1st image file is live(embedded as base64), but others are dead, `src="https://paper.dropboxstatic.com/static/img/ace/emoji/2753.png"` is embedded.
Now I only wish fix this bug, or is there any way to download full html all images embedded ?
