Just a guess, but perhaps you need to reduce the dimensions:

<img src="images/designjet.png" class="magnify" style="width:200px; height:150px" />


<img src="images/designjet.png" class="magnify" style="width:100px; height:75px" />

But it could be something else, or this and something else. If you want more help:

Hey i seem to be having the same problem - all installed properly but there is no effect. Could you let me know how you resolved the issue?
