Worth1000.com An ad-supported website running dozens of contests simultaneously to find the "best" in altered images, in many different themed categories (such as Visual Puns, and Stupid Protests) that change constantly. Viewers may post comments about any photo. Teachers: visit first before sending your students here, a few images and captions are for more mature audiences, but most are very mainstream and usually hysterically funny. Excellent visual literacy lessons here, not only in the power to alter what we think is "real" just by using Adobe Photoshop, but also great lessons in how to transmit an idea or concept through images rather than words (hence the site name, from the American idiom, "A picture is worth a thousand words.").
