A system stores, in a database, different stock templates and also, for each stock template, a stock image to be displayed with the template. The system receives a user-designated image. The system then displays items simultaneously. Each item incorporates a different one of the stock templates along with the respective template's stock image. The system provides an image selector that is in a first position and capable of being switched by a user to a second position. Each time the user switches the selector to the second position, the system transforms the stock images in the displayed items simultaneously to the user-designated image. Each time the user switches the selector to the first position, the system transforms the stock images in the displayed items simultaneously to the items' respective stock images.
