System, method and computer program for displaying an image with a blinking portion. A first virtual image layer is defined in a first file to comprise a first background region. A second virtual image layer is defined in a second file to comprise a background region in one state and a transparent region in another state. The second background region is different in appearance than the first background region. The second virtual image layer is logically located on top of the first virtual image layer. The file defines that the second virtual image layer repeatedly alternates between the one and other states. A third file defines a third virtual image layer to comprise a symbol surrounded by a transparent region. The third virtual image layer is logically located on top of the second virtual image layer. The second and third virtual image layers are approximately a same shape and size as each other, are approximately superimposed on each other, and are located over a portion or all of the first virtual image layer. The definitions of the first, second and third virtual image layers are supplied to a Web browser. The Web browser is operated such that when the second virtual image layer is in the one state, the Web browser displays the second background region on a display screen surrounding the symbol, and when the second virtual image layer is in the other state, the Web browser displays the first background region on the display screen surrounding the symbol. Consequently, the region surrounding the symbol blinks between the one background region and the other background region.
