Adding html code and inserting pictures into threads

As the name states I cant insert html code (I have a code that makes whoever clicks it not have to type my name to add me on skype)
It only gives me an error message that is telling me that i cant post links

secondly I am trying to add some "live" pictures to threads but i only get an error message that is telling me that i cant post links

If you refer here, it states that you must get at least 15 posts (although I think it's 10 posts because it is based off the usergroups system not post system)

Once you get 10+ posts, it may take a while before you can post links because the ranks system updates once an hour
