How do you add a logo to your URL address?

You have to set the image tag nested inside of the hyperlink tags if you wish to use an image.

<a class="url" target="_blank" rel="nofollow noreferrer" href="/to/?target=http://www.website.com"><img src="http://www.website.com/image.gif" /></a>

But if you prefer to use the slogan or name of your company instead, replace the image tags with the text you want to use.

<a class="url" target="_blank" rel="nofollow noreferrer" href="/to/?target=http://www.website.com">Your text here</a>

Whatever you put, image source or text between the hyperlink reference tags, will become click-able and link directly to your site, or whatever website address (URL) you put in the reference tags.
