URL encoding does not behave as expected

[nononoah]

It seems as if the image source is expected to be url-encoded. When a source URL is passed that correctly references the underlying file's source, the request fails. Instead, a url-encoded request must be made for that file.

I'm not sure if this is an bug, per se, but there should be clear documentation around this behavior.

Example
