Find a grave says that membership is free and that you can sponsor a loved one's site and post pictures. They do not have a complete set of rules anywhere on the site.
They make them as they go.
Instead of helping and being understanding to other's grief they are the most rude administrators I have ever been in contact with. They have a small group of forum members that are giving preferential treatment and if you ever disagree with them your memorials and sponsorships are gone. They will delete a loved ones memorial in a second and give no consideration to your grief. Admin's will not contact you for any reason except when they want to give a rude response to you.
Not a site I would recomend to anyone. Very poor management.
