Why are there 3 different files sizes of each photo on the Costco Picture CD?
A number of different size files of each photo are included on the CD. Each size is used in a different way. The Image Viewer software uses the Small images. This image is usually referred to as thumbnails and is approximately 4kb in size. This size is too small for printing. The Low images are used for e-mail, as their file size will allow for quick transmission over the Internet. The low file size is approximately 100kb in size depending on the image content. This size may be suitable for printing a small print, but will lack image quality. The images that appear in the Pictures folder are used for saving to the hard drive, editing with the included Photo Editor software and printing. The size of the file will depend on the camera that was used to create the image and the method used to scan the negatives. The Pictures folder will contain the highest JPEG resolution images available.
