Confirmed!  Just as Jeremie did also.  I'd seen this image-switching behaviour 
before and hadn't been able to recreate it with a simple example, but there it 
is.  "This is very strange," indeed.

I don't know if this is useful, but:

16.  Edit source code back to 300x300
17.  C-c C-c yes
18.  Image disappears
19.  C-c C-x C-v
20.  300x300 image appears (a new one?  or the first one?)
21.  Move the cursor to the image
22.  The now incorrect 500x300 appears while the cursor is on it, same as 15
