I only put pictures I like downloaded mostly from face book . I do ask the person I get the pictures from permission to use their pictures or if artist their work. I do not always know the titles of pieces as not always with the work when I download. I therefore add captions for titles if real title unknown, if it has just all the numbers it is because I can't think of a caption for that piece or do not know title. If you see numbers on a piece and know either the title or think of a caption for it I will welcome suggestions as long as you are aware myself or you can not take the credit for the art work unless it actually is yours or mine.
