403 errors

[sbpoole]

I've been getting a lot of errors logged on my webhost's server.  The most common is 403.  I get some 404's and lots of forbidden errors.  I have never had this problem at home, but at work my site never loads completely.  It has missing thumbnails and graphics on the home page.  At work I am on a LAN through a system network.  At home I am on dial-up and have never had any errors.  A couple of customers can't get past the forbidden errors to view their photos.  Any suggestion?  You can check out my site at //www.sonnypoole.com and see if you get errors.  Thanks for any help, Sonny

P.S. My webhost has closed down and another host has taken over the account but I don't know who they are yet, so I can't contact them for help yet.
