Add icons to profile picture and likes

Dear 7th Queen,

I have 2 questions I´m hoping you can help me with:

1. Is it possible to add a small icon to profile pictures? My dating site is for people to find a date or fitness friend, so what I´m hoping for is to add an icon of a “heart” for people who is looking for love, and a “training” icon for people who´s looking for a fitness friend after they are registered.

2. Is it possible to add “likes” to a comment and/or pictures so the people who is the owner of that comment or picture gets a message of who liked it. Just like Facebook.

Can you help me with this?

Thank you
