A system and method for editing and outputting an image, for example, for wall or other décor. Tools enable a user to parse a single image, such as a photograph, substantially automatically across a grid of multiple tiles. In addition to parsing, various kinds of image editing are provided as a function of tools in an innovative graphical user interface operating on a smart phone or one or more computing devices. Various operations are performed on an image that has been parsed across a grid of multiple tiles to provide for a custom output, such as for displaying an image uniquely on a wall or other surface.
