Speeding Up Loading

When I view the source code for my site, I see a script that contains all the categories that I have assigned to images. Almost all of the images are not in use, yet this script loads :

<script type=”text/javascript”>/* <![CDATA[ */var mcm_taxonomies = {“mlo-category”:{“list_title”:”View all MCM categories”,”term_list”:[{“term_id”:”no_category”,”term_name”:”No MCM

]}};/* ]]> */</script

As you can see this script is huge so I would imagine that it slows down the loading. How can I get rid of this?

I don’t know much about coding, so I have no idea where to start looking to fix this. HELP!!!!
