There plenty of sites for earning additional money online, and here is one for microworkers. It is a crowd sourcing site where you can solve simple tasks, click on ads, sign up in sites, vote for pictures, videos events, post in forums, yahoo answers and so on. Basically you do what the employers on the site ask you to and in return you can earn small sums of money. From 10 cents to 1$.
When you have reached a minimum payout, microworkers will mail you a pin code and the sum will be payed out via paypal. So yes it seems this site works well,

You see your pictures quicker. Most digital cameras allow you to view your photos immediately. There is no waiting and worrying about whether or not that “perfect shot” turned out. You can take a picture of that new baby and immediately download it to your computer to share your good good news with friends and relatives. There’s no need for anxious grandparents to wait days or even weeks for a picture.

The easiest way to decide what to look for is to know what size prints you are likely to print from your camera. A one mega-pixel camera is fine for those who don’t plan on printing photos but rather just post them on the internet. A small print, say 4 x 6, will print acceptably from this camera.
