Hi, your websites’ url please.
Now go to post editor -> Text Mode & then add class style-up-img like this
<img class=”alignnone size-full wp-image-6 style-up-img” alt=”On The Shore” src=”http://www.yourdomain.com/style-up-images/wp-content/uploads/2013/04/on_the_shore.jpg” width=”300″ height=”201″ />
You have activated the plugin but didn’t added the class.
I did add the class in the post, but had removed it before you saw the site. I’ve since tried and failed several times. Below is, first, the existing code. Secondly, is the code re-written as you suggest…it can’t find the image. I can’t see where I’ve gone wrong. (the code is no longer in the post)
<img src=”http://www.emrys.org/blog/wp-content/uploads/2013/05/Bonnie.png” alt=”Bonnie Adamson” width=”150″ height=”187″ class=”alignleft size-full wp-image-8202″ />
<img class=”alignleft size-full wp-image-8202 style-up-img” alt=”Bonnie Adamson” src=”http://www.emrys.org/blog/style-up-images/wp-content/uploads/2013/05/Bonnie.png” width=”150″ height=”187″ />
Can you please add it again. Need to check what is the issue.
