@JosephEchewisi no problem.
Also, depositphotos has a free stock section.
And I have to say this because I might die if I don't, pinterest and wewheartit serve as galleries, the sites don't own any of the photos and most of the pinned and hearted photos are not placed there by the owner of them. Somehow most people believe it's like a free market of photos,art and similar. As a wannabe designer, I think it's always better to go with free stock because they come in much higher quality than most pictures you can find on gallery-like sites.
(For vectors and such, there is freepik and vecteezy, but you have a limited daily download and you have to attribute the owner)
