I built my website using the visual editor,which worked well.
I now have to 'place' the affiliate's banner or button,which is in HTML ,in just the right position on the webpage(i.e. left or right side,top or bottom) How do I do this easily without becoming an overnight expert in HTML codes? Thank you for your help and suggestions.

You need to click on the code editor tab
before you paste your affliate codes.
Your code will show as text ONLY
NO Banners if you add it in the Visual View.
Wide Banners you need to place in the widest sections
so they donot overlap other items in other sections.
Small affliate images will be easier to
place.
