there are a lot of images been posted lately that are clearly using uncredited stock images as part of compositions. please remember to credit and link your (legitmate) stock sources and ensure that you have the right (public domain) to use them. Google image searching does not come into this category :-/

Images that are uploaded without the proper credit will most likely be rejected as moderators do not have the time to scour the net to check for the sources without having appropriate links. thanks.
