Attribution means giving credit for that picture and the file person.Giving attribution is showing respect for their work that they did,furthermore when you are to use someone’s picture then you should be kind and give the attribution to the picture.  I was confused of how to give the attribution but then I remembered how to. It’s not respectful to not give attribution to a picture when you should, imagine someone woke up 3:00 am just to take a picture of a sunrise and edited for six hours for a perfect picture. that is reasonable for some and if you know you gave attribution then when you hover over your photo you picked it will show it.
