I dont know the exact law here - but as long as you arent liabeling someone saying they are doing something they arent - you should be ok. In any case, in regards to disabiality - even Medicare defines "homebound" as a person who can leave the house to go to appts, meetings, church, etc... not locked in their home. You may run into folks who dont want their pictures posted anywhere for various reasons, I'd just ask them if anyone has any objections.
