Why does Captcha field show the input field to the right of the graphic instead of under it?

Are you referring to your JotForm titled "PeeWee Contact Form"? As I check your JotForm, the captcha field seems to be displaying properly. 

If you are referring to something different, please let us know. We will be happy to assist you.

 

 

 

That is the one I was referring to, but I decided to delete Captcha because
I found a post that said you have other ways of stopping spammers and only
offered Captcha because people requested it.
Is this the case? Or is Captcha really necessary to stop spammers from
hijacking a form?
