Help, please

I'm enjoying my first day at ATS! However, I need help/suggestions with the following:

As I studied Zedd's handbook and other pages for newbies, I noticed that the image of the ATS "button bar" had cute, colorful little graphics on each button. (The image I reference is just below the "Basic Navigation" topic heading on the 1st page of Zedd's shown when you click the "home" button.)

My ATS buttons are just ugly old greenish/gray with text that is either light green, blue, or yellow.

I do, however, see other graphics on ATS, for example, on the left side of the heading
line for the Freshman Forum, there's a green circle with a question mark and file folder.

Is there a setting on ATS, or on my computer (in Internet Explorer, Windows, Internet Options, etc.) that will enable me to see these graphics?

THANK YOU, in advance, for your help and suggestions.

The buttons you see now..are recent, only for a few months..Zed's book just hasn't been updated yet.
