Copyright, in my opinion, is very important, especially if the creator is not a large individual ;) Sometimes a photographer will take a photo that he will sell to a newspaper for $1,000 (or something) and by copying his work we can break copyright.
On Steem, people often warned against making money from someone else's work and it's possible that it's going to be like that in Zapread. That's why it's worth showing you Pixabay.com
Pixabay.com is a website with free images that can be used even for commercial purposes. Thanks to an intuitive search, in a few moments we will display all the photos we are interested in.
It is worth remembering that Pixabay does not like hotlinking, so you should copy the photo and upload it to the Zapread server (or another provider of photos).
I hope you enjoy the website :)
