As said, Gedcom files are text only. I think version 5.5 allowed embedded media, but this stops the text only editing. V5.5.1, latest but unofficial version, allows the media to be kept in related folders, and everything zipped for transport.
Unfortunately, zipped files are not good on the Web and Wikis, not only for security reasons, but also because items on the Web and in Wikis should be individually addressable with Web compatible addresses (URLs) so that they are easily addressed and discoverable.
So no easy effortless path. Chris Little-4631
