I know for stock photo's the answer might be yes but certain pictures on Google are eather pictures from videos on Youtube or informational websites, plus I wanna make sure I don't get in trouble for something small.

Hello! Stock images are good to use (Pixabay, Unsplash, etc), since you know the rights for use of the image. Do NOT use images you just picked off of Google, since you do not know the rights of those images or the person who made them. Do not use images that you do not have explicit permission for.
