Low for the Web and high for printouts. Without an optical viewfinder, you must compose your picture live on the LCD monitor where sunlight can produce a glare on the glass that sometimes makes it impossible to see outside. Holding the camera at arm's length can also encourage instability when snapping the shutter, producing blurred pictures. Built-in is even better, as far as I am concerned. Buy a camera that has removable media, i.e., some type of chip, card or floppy that allows the pictures to go from camera to computer.
Every camera is different.
SmartMedia cards even have a standard floppy disk adapter. If your camera has the compact flash or SmartMedia cards and your computer is a desktop, buy a PC-card reader for your desktop. Don't do cables. These cameras are not just for flyers. The cameras and resulting images will become the presentation.
