Depending on the country of origin and first publication, yes it is probable that they are the subject of both implicit and explicit (registered) copywrong, and will remain so until the term expires ir the evil copywrong system is overthrown. –  Frank Thomas Dec 19 '13 at 14:16
    
How does this relate to computers or software as in the help section? –  Carl B Dec 19 '13 at 17:20

You should not think that the lack of a Copyright mark renders them free. In most jurisdictions copyright is automatic as work is created.

@ChinmayDabke, no that is the opposite of what he is saying. you may NOT use them, unless you get a license from the creator. they do not have to marked as copyrighted for you to be sued over them. –  Frank Thomas Dec 19 '13 at 14:18
    
No, unless you find the author (or current owner) and ask him to give you a grant on write. An android app would not even justify "fair use". –  Envite Dec 19 '13 at 14:19
    
As an example: See the image in this blog post: fantaciones.blogspot.com/2012/06/el-reino-de-saban-grecie.html The image has no copyright printed on it, nor in the metadata. But the image is mine, I drawed it in 2012, so I have Copyright on it and I will sue you if you reproduce it. But at the end of the blog you find a License where I give you some rights about the entries. If you find something similar in the webpages were you get the images from, you can use them. Otherwise, you can not. –  Envite Dec 19 '13 at 14:23
