Hi Carsten,

The dependencies are async, dnd and wget.

In case dnd doesn't work, there's a fallback to clipboard via
`current-kill'.

I've just added a custom variable that takes either 'wget or 'curl as
the download method.

I tried before url-retrieve, but it was giving me some garbage in
addition to the image. So unless I know reliably the format of the
garbage I can't use url-retrieve. But if I figure it out, I could add
url-retrieve as the third custom method.

The updates are at https://github.com/abo-abo/org-download

regards,
Oleh
