Each week, iStockphoto features free downloads from its galleries of royalty free stock photos and other media. Simply go to www.istockphoto.com, scroll down a bit and look on the right side of the page to see the free downloads of the week for images, illustrations, audio, video and Flash.
Now, what I didn’t know and found out about maybe a week or two ago is that iStockphoto offers very nice free backgrounds for your desktop each month. These themes backgrounds include a monthly calendar and are available in a few different sizes: 1200×800, 1400×900, and 1920×1200. For April, I am definitely enjoying the retro images that they chose.
