Stock agencies offer the possibility to sell or buy pictures (photos and other artwork) or videos (footage).
On stock sites you can search in the portfolios of many photographers.

On this page are links to several stock sites where I have a portfolio.
If you want to sell or buy photos or footage yourself, you can click one or more of these links and create your own account with the stock agency of your choice.
Feel free to use the Contact page for more information or some help.
