Sometimes it is necessary to control the vertical spacing in your WordPress blogs, especially around inserted pictures.
My solution is the following:
In the WordPress editor go to the HTML mode (the tab labeled as “Text”) and insert this command in a specific place in the text
<div style="margin-bottom:3em;"><span style="display:none;">.</span></div>
You can control the vertical space by changing “3em” to “5em”, “10em”, etc.
