Stock sites, tutorials and Photomanip groups

Examples of good stock sites

Please note that this list is meant to give an overview of available stock sites that we would recommend to use, but it is in no way meant to be complete, and we do not take responsibility for the legitimacy of every photo uploaded on these websites. We recommend that you check the rules of every stock photo you download there and the specific Terms of Use (ToU) of the website.
The following list is divided into several subsections, paid and free stocks, and attribution required or not required.***
What does attribution mean exactly? It basically says that you're obliged to credit the stock provider whenever you use their stock in your work.
