I think my issue is more on the TMG side. If you do an export with TMG, you will see that it does allow you to include external images. I believe that mine are all internal, so they do not get exported with the Gedcom file. I am just trying to clarify if that is correct, and to find out if there is a work around.
By the way, from the little that I have seen, I think the Gedview app is an incredible bargain and head and shoulders above anything else out there that I have seen for TMG on the IPhone.
I used to use the Northern Hills software on an earlier phone, but they don't support the IPhone.
