Can I use the photos I buy from Dreamstime in more than a single project?
If each project is different as a concept (not a template based presentation) then you can use the photos for more than one client, you don’t have to buy them twice. If the concept is the same you cannot use the images because this will be seen as redistribution. The total number of copies shouldn’t exceed 500,000 copies. Note that if more than a single person within your company will be using the image, then you will need to license it using the Unlimited seats (U-EL) extended license.
