WampServer

I have one site that is a high traffic site, but i'm on a T1 connection, sometimes the photos do not load is this an apache error? or a wamp setting that is incorrect?

example: [www.myzeebo.com]
** surf the other profiles for a bit, sometimes the images won't load **

Thank you in advance,

Brad Trammell
