improve my social network

i recently created a social network. it has looks and functionality similar to facebook. it has been coded in html,php and jquery and has mysql database. i need to add the following things 1 - install video chat script and configure RMTP server OR install a simple chat script similar to gmail or fb 2 - add facebook like notifications (using php and jquery) 3 - show a loading image whenever and ajax request is sent. 4 - add an option to include images inside the text of blog while posting it. 5 - i have added a "like" button. i want more such buttons. like "dislike","superlike","gross","dumbstruck","wink" etc. The code will be easier to implement. i will give you the database architecture and you'll also get small pieces of code that you'll need while coding.
