When you adding images into tabs and want them position on sides you will need to insert html class to position them.
class="float-left" will position images left
class="float-right" will position image right.
Here is example how you need to add class to the image to position image to the left.
<img src="http://pixel-industry.com/wordpress/elvyre/wp-content/uploads/2014/05/servicesdevices.png" alt="services" class="float-left">
If you placing image on the left side i recommend the you put image before text, and if you placing image on the right to place image after the text.
If you need more assistance feel free to ask.
