Copyright Safe Photos from Adobe Stock:
Using images from the internet can be tricky. Photographers are not required to watermark, or indicate that their works are protected. Some individuals will set up scans (I call them trolls) to catch their photos on internet websites. They will hire law firms to go after the business owner, not the designer or advertising agency – usually for thousands of dollars in damages.
I use only copyright free images, either shot myself, or from my subscription to Adobe Stock. A.S has tens of thousands of very high quality images, like the one below I licensed for a Process Server website a manage.
