So you have a lot of photos, you like to take pictures? Actually you could make some money from that. The only thing you need to do is to sign up for one or more of the photo-selling-services that are avaliable on the net. Then upload the best pictures you have and pray for the best. Now do not believe that you just can upload any picture and sell hundreds of them, it is some competition out there! But if you are a good photographer, have a good camera there's a good chance for you to succeed.

The biggest player out there would probably be iStockphoto. They have a huge collection of images, they also have a lot of customers so there's a good chance your picture will sell. They have sections for images, flash, audio and video. Sign up and start uploading!

Another service is Mostphotos. They do not review your photos before you can publish them in the website. There is a minimum resolution of 5 Mpx. Take a look at their 'What's selling' list to get an idéa on what to shoot. A picture costs 25€ in their website and from that you will get 50% or 12.5€. Find out for yourself by signing up and start uploading.

There are lot's of other photo-selling websites out there, but these two are good for a start.

Good luck!
