Pictures for your printing
In the past we referred you to an on-line retailer of images and photographs. These images were very expensive to purchase. You can still use these sources ie. gettyimages.com, photodisc.com, etc.
We now recommend that you first search the internet by using, for example, Google's image search. Searching for "large" and "extra large" images will generally give you images with enough resolution to print from. You save the full resolution image to your desktop rather than the thumbnail image.
