It seems to be some sort of unibyte/multibyte confusion bogosity (not
sure if the code in url-*.el or mm-*.el really does that sort of thing
well or not).

If you do (set-buffer-multibyte nil) in your temp buffer before
downloading the contents, it should work; e.g. the following
successfully inserts a GNU head image for me:

   (insert-image
    (create-image
     (with-temp-buffer
       (set-buffer-multibyte nil)
       (url-insert-file-contents "http://www.gnu.org/graphics/gnu-head-sm.jpg";)
       (buffer-string))
     nil t))

[Note the third arg to `create-image' tells it to try deducing the image
type from the data in the image.]
