I noticed a new feature on LinkedIn where you can upload a background image. I then found this website that offers images to use. Can any image be used even considering LinkedIn profiles are meant for personal profit, in an indirect sense? Nowhere in the linked to site does it explicitly say "you are free to use our images" but can it be implied?
You can't use a copyrighted image but often times on the internet you don't know what the license of the image is. How do you know what the license for the image is?
