Please refer to the guide [guide|31194|Connecting Camera to Computer] for further information. Also make sure that the proper software is installed to your computer. This software should be on a CD-ROM which comes with the camera. If you do not have the CD-ROM the software can be downloaded from [http://www.usa.canon.com/cusa/consumer/products/cameras/digital_cameras/powershot_a4000_is#DriversAndSoftware|Canon Software and Drivers].
