Please add a blank line above to separate the two types of "images".

node.name() above returns something akin to "IMG", which is an HTML name of the tag, as opposed to "HTMLCanvasElement", which is a DOM type name. Inconsistency ensues.

No, node.name() returns URL of the cached image. We don't have user-friendly name yet so return generic name.
