Quote by: Lee GarnerImages should be JPEG (either jpeg or jpg extension). The size is limited to 4MB, but really anything around 800x600 pixels at 72dpi will be fine. Images for the web don't need to be high resolution. Software like Photoshop or Irfanview have a selector for image quality, and 80% - 90% is plenty.
