Word Press Website bug fix

Recently moved my wordpress website from one domain to other that resulted in images of the website not being shown. I doubt its something related to the execution of timthumb script or it could be something else. Need some one to fix the bug to get the website up and running. Additional task is to integrate the website with 2Checkout Payment gateway. The plugin used for Products in website is Dukapress so what we need to do is get the dukapress plugin updated to enable 2Checkout payment gateway.
