When I copy and paste an Affiliate's code - (for an "image") - onto my Website. What I see - (when I press the "view buttom" of my Website) - is the code: instead of the image.  

I am sorry that you are having that problem. However, you posted your question in the wrong place. This area here is used to review other websites. Please re-post your question by clicking the "Ask it" tab on the top of this page or just go here:

Hello, are you trying to paste the code directly on the page? 

Most of the time codes will work in the "HTML Module".  Try pasting the code in the "HTML Module" when editing your website, then save and view to see if it appears correctly.

If that doesn't work could you (like Ken stated) re-post your question in the forum?
