But they are offering a form of payment, aren't they?

It's just not in the form of money. It's a photo credit. Which perhaps could, in sufficient aggregate quantity, be eventually transformed into money down the road. Not all types of compensation take the form of money. At least not immediately. Value can be transferred in many ways.

Now whether the value offered is sufficient to cover the deliverable is another story, and can only be ascertained by each individual considering the offer.
