I need to add a wrapper (I'll use
<figure> in my example) around images posted through the editor, with a variable depending on the size image is being posted (thumbnail, medium, large, full), something like:
<figure class="$size"> <a rel="attachment" href="....> <img... /> </a> </figure>
I already solved the first step, adding the wrapper with a filter through
image_send_to_editor, but I can't find a way to get the image size so I can add it to the class.
