A browser's Copy Image puts the picture on the clipboard with text next
to it. Paste already took the picture when that text was only the
image's address (#597), but some browsers (seen on Fedora with KDE) put
the image's HTML there instead, `<img src="…" class="…" style="…">`,
which isn't an address, so the markup was pasted as type.
names_a_picture also takes markup whose only content is <img> elements
(no text outside its tags) as naming the picture, and Paste then reads
the bitmap. Markup with words in it, and an address alone, still paste
as text.
