Second thought, do you have an ad blocked on? In that case you block your own adds too

You should add the banner images to your wordpress media section first by going to your media library, then "Add New" click on "Select Files" and go to where you have the banner image and save it. Then when you are in your post in the visual part rather than the text part, click your cursor where you want the banner, then click on "Add Media" above the box and select the banner you want and follow the instructions.

That's the only way I know how to do it but it works
Can remember how to wrap the text though

I know I've been having trouble with my banner as well, Not sure what's going on. May have to contact support.

You need to paste the HTML code - starts with a herf into a text widged or in your text tab
