Was just checking around a bit and saw that there is a way to work together with istockphoto and sell your pictures...
Their requirements are below for anybody interested...

Images that iStock does need:
* Corporate shots: Illustrate the many sides of modern business.
* Concepts and Visual Metaphors: Go beyond the literal, and help a designer explain something in a new way.
* Food and Beverages: Cuisines from around the globe.
* Groups & Teams: People working together.
* Holiday & Seasonal Themes: Show all the ways we celebrate. Include more than religious celebrations; let's see local festivals and customs as well.
* Non-Business Jobs: The word is filled with mechanics, garbage men, baristas, and more.
* People Interacting: Human interaction is a constant in this world.
* Religion and Spirituality: The rich tapestry of the world's beliefs.
* Science and Technology: Accurate and true depictions of the cutting edge of human knowledge.
* Social Issues: Poignant looks into the issues that impact us.
* Sports: For fun, for fitness, for glory. We'd love to see more team sports.
Images that iStock does not need:
* 3D – Simple Renders: Go beyond the easy and obvious presets.
* 3D – Extruded Text: Simple 3D text is not enough.
* 3D – Simplistic Modeling: Spend more time with your polygons.
* Airplane Wings (& out the window shots): Wait until you land to shoot the vacation shots.
* Flags: 3D or real, give us something more than the basic flags.
* Light Blurs: Fun for photo clubs, but rarely is it good stock.
* Nature Snap Shots: Sweeping vistas and insect macros are great – yet another forest floor is not.
* Photoshop Backgrounds, Fractals: We've all had fun with filters. Designers are looking for images that they can't quickly make themselves with a few button pushes.
* People Doing Nothing: Get your models doing something!
* Shadows of People, Headless People: Photograph people or do not. There is no try.
* Single Apples (or Green Peppers or Oranges) Isolated on White: The day of the single fruit isolated on white has passed.
* Sunsets, Cloudscapes, Skies: Be sure the sky really is stunning before uploading.
* Symbols: !$%@ – Whether rendered or photographed, typographic symbols are less interesting than you think.
* Your Immediate Environment: There's life beyond your front door!
I just wonder if anybody in here is familiar to this and can tell me a little bit about how easy or hard it is?
