How do I know if images are being saved to the internal memory or to the optional xD-Picture Card?
The internal memory and xD-Picture Card cannot be used at the same time. When the card is inserted the internal memory is disabled. When you want to use the internal memory you must remove the xD-Picture card. The LCD display indicates the images are being saved to the internal memory by displaying [IN] in the lower right corner of the screen. When using the xD-Picture Card the LCD will display [xD] in the lower right corner. These indicators are displayed just above the number of available frames.
