Text on the geolocation maps page

Hello, I'm not sure if this is possible, but I was wondering if there was a way to add text to the maps page created by the geolocation plugin? Currently I'm unable to figure out how to add some introductory text above or below the map.

Additionally, I wanted to get rid of the "Find an item on the map" text that's located to the right of the map (ideally, i'd like to center and stretch the map across the screen, but if that's not possible I'd just as much rather edit the "find an item" text). Are either of these things possible?

Sorry, to specify this problem is for an omeka.net site.

That isn't possible for an Omeka.net site. If you have other related questions about using Omeka.net, please use the contact form for further assistance: http://info.omeka.net/contact
