Images and photo's on websites sometimes contain copyright. Never use them without the approval of the creator.

And yes Pinterest is one of them. This website is good to have ideas but to copy and paste the photo somewhere else is a big nono. People repost these pictures all the time without mentioning the real creator so it's hard to find out who made it in the end.
(So watch out, Pinterest is full of traps.)

To avoid that I have some websites that can help you.

Mostly it's mentioned 'free to use' 'free for commercial use'

If not ask the creator first or leave it alone.

Or if you have a good camera on your phone take the pictures from where you live or where you go on vacation yourself. (Watch out with taking pictures of people!)

I do it to and post them on Flickr.
