So my cousin has been travelling through Asia for the past 6 months (India, China, Nepal, Vietnam, the Philippines, A couple others) and has been taking just...tons and tons and tons of pictures. He decided to .rar them all up and send them to me. There are thousands of pictures but one giant, giant problem. Whatever he was doing with them resulted in the .rar having multiples of many of the images. They're all named differently however. I was wondering if anyone knew of any programs that find duplicate images that doesn't match the file names but scanned through the images themselves. It would be really awesome and would save me hours and hours of going through all the pictures. Thanks.
