Blog post Image breaking layout

It appears you image is being “floated” to the left (or right, as the case may be) which is a common CSS style in themes.

A possible fix is to put a “clear:both” div just before the end of the_loop.

<div style="clear:both"></div>

Add the above code into the_Loop (using the example from the above link) just before this bit of code:

<?php endwhile; else: ?>

… in your theme’s index.php template file.
