An easy way to get postcard design ideas is to look for photos or illustrations that work with your message. To avoid breaking copyright laws, you should buy a photo from an online source.
iStockPhoto.com is my go-to place for professional quality photos and illustrations at reasonable prices. (Click the link for 10 free credits, no credit card needed.) They allow you to purchase a smaller number of credits at a time, which is convenient for small businesses.
