Exposing inline images to Views
If an image is inserted into a textarea like your wysiwyg editor, the node does not retain an entity relationship with that image, you would need to parse the full content of that field for images, figure out if they are internal, get their ID...

Your node should ideally have a field of type image, that way your saved node has an association with one or more images you have uploaded. You can then insert the images inline wherever you wish.
