Plugins stopped when i import Jquery.min.js from CDN

Question

hi, i used Plugins for Photo Sliede and PhotoZoom.

Now i want to use Ajax so, i use
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

 

When i import above jquery plugins and photozoom are stopped working,
and when i remove it, plugins are completely work.

So i cant understand what is the issue ?
