A web-enabled resin panel customization website, hosted through a web portal, provides, through a client computer system, one or more user interfaces configured to receive a plurality of user selections, and provide a realistic display of the resulting output. In one implementation, a processing module overlays transparent portions of images representing a translucent resin substrate with one or more images representing decorative objects, films, or the like. The processing module can also combine pixel information from each of the added/overlain layers. In either case, the processing module sends a combined pixel data stream that can be rendered by a client system, and thus provide a user with a realistic depiction of the user's resin panel selections. The customization website further includes one or more user interfaces that enable a user to store specific resin panel design profiles, and order resin panels corresponding to those specific design profiles.
