Hello there good sir. It has come to my attention that some of the artwork posted on your wondrous site has been prohibited of use by the artists who created them. Furthermore, a lot of the art is missing credits. If it is no bother, may you please add credits from the art that you know is public and you have permission to use, and also remove the art you got from google, and any other art which you have no knowledge of such being public, or if you do not know the artist responsible for it?
Thank you dearly, and I hope you have a fine day.
~ Sir Marc Anderson the Great
That any better?
