Oh my gosh! I did not even think about that! I am so stupid! Should I take it down? Thank you for pointing that out!
The general rule (to avoid falling foul of copyright law), is "if you didn't take it or make it, don't use it."
If you ask, the owner of the image may give you permission, but you should not use any photographs you didn't take yourself, unless you have permission. This also applies to posting images to discussion boards, flickr and photobucket accounts, etc.
Also, it is simply good manners to check that the Sisters are OK with appearing in something they didn't create - they may be happy with their photographs appearing on their own website, but a YouTube video that they did not create, and thus is outwith their control, may make them uncomfortable.
