I want to make videos where I read creepy stories/urban legends/creepy pastas/etc, and play images in the background. Like many of the other scary videos on YouTube. My question is where or how can I use images in my video without getting a copyright strike. I want to be able to someday monetize my videos so I don't want to have videos with copyrighted stuff in it. Where do people get the images they use in their videos to avoid getting a copyright strike? Do I need to sign up for a stock photo shot? Would that even work to prevent the copyright issues?
