I have found that the imagery can be transfered within a dwg file. But who ever the dwg goes to has to have 2013 and Basejump. Basejump is only a technology preview and The technology preview will operate until August 12, 2013.
You may want to reconsider using Basejump for deliverables.
Unless Autodesk moves this preview forward it will go away.
Brian Hailey has an alternative here
How are you using the imagery? ie as an underlay for plan sheets.
The workarounds that I have to get the Basejump imagery so to speak, saved, are not really all that good for deliverables. The dependency to Basejump will remain for one workaround and the other is to create dwfx files with map info of the selected areas of the imagery. However the dwfx file can be used as an underlay but the quality is not near as good as the original imagery.
Given the time frame to get your project out the door and that what I have done is not tested enough to risk disappointing a client, I feel other imagery options should be explored.
