It's not clear what might be causing a slowdown on your images loading. It's a bit harder to troubleshoot GoCentral as it's a proprietary product of GoDaddy. Your best bet is to give support a call and have them take a look on this one. They have tools that will help them diagnose, and hopefully correct, the issue for you.
