If implemented, I would prefer this were a more general CC image search, covering Flickr, etc, as well as Wikimedia Commons.

Also, I presume this would be part of "insert image" popup in the update page? It might just be the options I have selected, but I don't see that popup in the new (beta) create entry page. Whatever happens, it will have to tie in to the new design. brainwane, it might help your case if you were to suggest some of the UI/workflow and/or how it might fit into the new create entry page.

But more generally, I agree with elf that DW is strongest for mostly-textual posts, and that it would annoy me to see people putting images in their posts based on keywords, because that has a whiff of "INCREASE YOUR BLOG TRAFFIC!!!!1" to me (possibly because it's the style of many link-baity commercial blogs), and that's not what I want DW to be about. OTOH, if other people want it, and it's just part of the "insert image" popup in the editor, then it's no skin off my nose.
