it was an [img] link, not an upload..
(I could tell by clicking 'quote' and viewing the source)
Still not sure how to do it
Well...I clicked on quote on Ursus's post, and toward the end of her post, was able to see this:
[img]http://g-ecx.images-amazon.com/images/G/01/ciu/2a/2b/9734024128a083e93e768010.L.jpg[/img]
As the content of the above link indicates, it points to an image on amazon's server.
