Susan, Reba's post is incorrect. The IGI and the Genealogies section of FS are two totally different things. The first is an index (not family trees); it is indeed no longer being added to, but that's neither here nor there for our purposes. The Genealogies section is archived family tree files (GEDCOMs) submitted by users of FS. You can submit your own file by going to FamilySearch - Search - Genealogies and clicking the "Submit" button near the bottom of the page.
I don't know what Genealogies does with images. As far as I know, the GEDCOM format doesn't actually include pictures, only pointers to them (which of course are useless for portability), so I think you need some other site/service to archive those.
