How do you upload custom images on your Portal server?

I want to use custom images for a custom template. Don't really feel like going full out HTML (unstructured UI template). On my Portal, I want to place it under Navigator/Applications/Shared Components/Images. This is where the list pulls from so I go there and the "?" for creating custom images says I need:

"The /images/ virtual directory path is set in the Oracle HTTP Listener plsql.conf file"

I see the configuation and install of HTTP Listener but can I do this remotely? I've got DBA priveleges on the Portal btw. All help appreciated.

C'mon people, I know someones got to know this. I need to somehow map a virtual drive to the location of the images, files, etc in order to use it in portal. But can this be done remotely with DBA priveleges in Portal, that is the question :confused:
