If you are going to be using photos I suggest you use this website.
IF you use pictures from a Google search you may get sued by the person who took the picture.
If you don’t want to not lose any money I think you should use Unsplash.com.
I have used this site many times for my projects and haven’t gotten sued yet.
Do you have a copy of the image you created/a link where I can find it?
