Image output is broken

Issue Summary

The Image output is broken for me. I have several images in a node, like a block. After generating the PDF, all the images are in a row and not in the block form as in the node.

For example, the node:

image image image image
image image image image
image image image image

Broken PDF output:

image
image
image
...

Node source code:
<a href=......><img ...../></a>  <a href=......><img ...../></a>  <a href=......><img ...../></a>  <a href=......><img ...../></a> <br /> etc.
