It seems that it shows up only the /images/pcb1.jpg right? AJAX extension seems to be your problem.

MS Ajax Extensions, necessary to run MS Ajax on the server has been made a part of .Net Framework 3.5, and every installation of .Net Framework 3.5 on the server automatically installs MS Ajax extensions as well. For .Net Framework 2, and 3, you need to install the MS Ajax extensions manually.

Download details: ASP.NET AJAX 1.0

Now just install it on the server.

Be sure that your server has or not installed FW 3.4 or above before you start implementing the above suggestion.

As mentioned it can be that you have a fw 3.5 on your workstation but not on the server. you see the difference?
