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.
