Before you deploy a .NET Web Forms project, make sure you add all picture files used by the application to the resource file list for the project.
Resource files might not be accessible if you change the default value for the initial current directory of the virtual file system for the Web Forms project. The default value in the .NET Web Forms Application wizard is the current target path. Modifying the PBCurrentDirectory global property in the project’s ASP.NET configuration settings or directly in the Web.config file might also make the resource files inaccessible.
