Reality check?

There are millions of people with digital cameras, a great majority of whom would like to sell their work. The likelihood of actually earning any significant amount of money simply by posting work to any of the myriad of web sites that claim to pay – is minuscule. There are a number of reputable stock photo agencies who do pay – but they have minimum standards for work – often demanding a professional level camera and extensive photographic experience. They also demand a model release form where appropriate and won't make payment without them.

Sites like Triond as someone suggested here are something to be avoided unless you want to give your work away.

Here is an excerpt from tiond's conditions:

"you hereby irrevocably and unconditionally grant Triond, and any of its affiliates (hereinafter also referred to as "Triond"), a irrevocable, perpetual, unlimited free of charge and exclusive right to publish the Original Content on the Site and/or on other Internet Sites"

They are under no obligation to pay you, but have acquired the right to publish your work. They pay a proportion of the advertising revenue for people who hit on a site containing your work – not for the work itself.

It might not strictly speaking be a scam but it certainly bears a strong resemblance to one.

To make money from photography without a recognised name is almost impossible. If you really want to try – then approach one of the reputable stock agencies. If they see some merit in your work they might take you on.
