This is now in beta and available for general download from
http://www.sjhaley.com/cupx/createcupx.htm

Cupx files are turnpoint files with embedded pictures that can be used
in LXNav flight computers along with Seeyou mobile. LX Navigation's
Zeus also supports Cupx but I have not tested it with that instrument.
This program can create a tp file using your own pictures and/or
Google Sat pictures for each TP
