I have my main family tree on Ancestry.com and I've added a lot of sources within the Ancestry interface i.e. the Sources appear with a small preview and a direct link to them.
With a lot of my family in other European countries, I've ended up using other genealogy websites to build the parts of my family tree in those countries and then exported the trees as GEDCOM files too.
As Ancestry.com offers no merge feature, I have used RootsMagic to combine all the GEDCOM and I'm quite happy with the result.
However, when re-importing the GEDCOM file into Ancestry, all my sources only have a title such as "Ancestry.com, England, Pallot's Marriage Index, 1780-1837 (Ancestry.com Operations Inc)" with no further details i.e. no preview image or link to the actual source.
Looking at the combined GEDCOM that RootsMagic creates, I see no _APID tags for my sources.
Is that the reason why my sources no longer have links?
Is there any software that can preserve those tags?
Edit: It looks like this problem is covered here actually: http://forums.rootsmagic.com/index.php?/topic/13901-importing-gedcoms-from-ancestrycom/
Does anyone know how to export the image URLs (not the actual images but since a lot of these URLs are public URLs in Ancestry) from Ancestry to GEDCOM?
