How to post Amazon Associates Banner Ad in Xenforo 2.2.4? I tried to post it using 'Advertisement' option, but it didn't show. Please help me.

Thanks in advance.

Update:

I got the solution of this. It can be placed with HTML widget. Very easy to do. Now I have to find out whether it can be showed only to specific user group or not.
