Currently, they are uploaded in private mode, and thus when accessed, they are accessed through jump.cgi

Example;
http://www.harveymilk.org/Details/537.shtml

At the bottom of the page there are attachments. Way down at the bottom. When you right click it, or click and hold for a macintosh, the image is named jump.cgi.

Must I switch it from private to public in order for it to automatically stay named what the image IS named? If so, do I have to re-upload them as public images?

Thanks, will try the url to download=1
