Thanks for asking. It is a problem for myself and photographers on Tumblr. As photographers we put a lot of time and effort into what we do and it doesn’t take long to give us credit. I’ve gotten jobs from people tracking me down from people that gave me photo credit. As a photographer our names are our brands, so if people don’t see our names/find our work then that affects us.
So yes, please do give us credit and don’t remove our credit so we can continue creating for you.
Thanks for asking! (I forgive you)
