amazon URLs for Scripto files?

I recently migrated my site to a new hosting service, and also activated the Scripto plugin. Filenames now appear as amazon URLs (eg, http://s3.amazonaws.com/omeka-net/806/archive/files/557926af6086cddf0e130d5b0a2acfe4.jpg). I am just wondering why that is. If I deactivate Scripto the URL disappears from the public page, though it remains on the dashboard. I'm not especially bothered by it, but when Scripto is enabled, it could lead someone think they are going to amazon.com.

It looks like that URL is the "name" of your file (perhaps because you imported it from that URL). The dashboard (and likely Scripto) are just showing what Omeka considers to be the "original filename," which for things inserted from URLs is the entire URL.

Setting a Dublin Core Title for the file (note: the file itself, not the Item it belongs to) should change what its name is considered to be, at least on the dashboard.
