I'm sure this will possibly warrant a tongue lashing from the moderator, the artist who created a video would like to link it from the Coppermine site to his site and unfortunately I don't know how to do it or if it's even possible.
Related to initail install? Use bbcode to link stuff. Use the MiniCMS plugin to use more advanced links. Not sure what you want to see acomplished exactly, sounds a bit vague. Board rules (http://forum.coppermine-gallery.net/index.php/topic,55415.0.html)!
We have a short video on our Coppermine page for viewing, the person who created it would like us to create some kind of I guess hyper-link to his own page for a more indepth viewing of his other works.
Use bbcode (http://coppermine-gallery.net/demo/cpg14x/docs/index.htm#bbcode) for the description then.
