Rodovid is a drag-n-drop genealogic program for Linux or Windows based on Tk, Perl. You can edit info (name, sex, dates of birth, death, marriage, etc...) for individuals, add/remove photos, import and export GEDCOM data, creating sites like http://www.mishchenko.tk.
Not sure why it was tagged as a genealogy program. ,,. not even close to being usable for that
