Create a nice intro for gaming site.

I need a graphic image for an intro on my website. This image needs to fit in the left column of my website, and will be visible for showing the features on the website. The image can show a little graphics, but mainly focus on the website features. Example features: Users can create a group and be admin in their own group. Groups have forums, events, images, videos. (that would be too much info, we might need to shorten that) Design profile just like Myspace 2.0, Facebook like features, Youtube like features, ect... The intro will look similar to the attached image...
