The images in iframe option looks fine. In DIV option the images shows an X (file dont found) because the path is taking the full permalink of page or post.
I fix it adding a / before the resourcesFolderName variable. So in wordpress is ok, in hype shows an X now.
The correct way to do it is with the slash; it should look like:
<img src = "${resourcesFolderName}/myImage.png">
This should generally work in Hype and Export cases to show the element; if not, it’d be useful to attach a zip of your .hype document and maybe a link to a wordpress post with it.
