Hello, my name is Jerry McElroy, and I have been a professional photographer for over 30 years. Since the early 90's, my pro-visions.com website was used to sell my stock images and it was pretty successful for about 10 years, then sales dropped off to about nothing.
The internet combined with the advent of digital photography has changed the business of stock photography forever. After looking at many of the micro-stock companies, I decided to go with iStockphoto, the lead dog in this business. Now, I am selling more stock images on a daily basis, shooting more stock, and having more fun doing it than ever before.
istock also accepts digital video clips and flash projects. And, no, you don't have to be a full time professional photographer to join. You just need to be able to shoot sharp, high resolution images that are well composed.
Signing up and becoming a member is totally free. istockphoto makes their money by selling the use of your photographs and then pays you a royalty. Once you upload a photo and assign it a description and add key words, you are done!
