Is it possible to generate the list of media/image files that are shown in the dialogs such as the Insert Image dialog ourselves in code rather than by specifying a file path? 

 

The problem we have is that the list of media are not in the file system.  I can generate the names and urls in code - just need some way of passing this to InsertImage.aspx, etc.  Any suggestions / examples on how this could be achieved?

 

Thanks
