All the images, are photographic that not you/they are considered by the law, "works of the talent" of creative character and as such they are subject to the right of author.

The right of author is originally purchased for the only fact to have created the work, it is not therefore necessary some fulfillment of administrative character, what deposit or recording. It is not possible therefore to reproduce a work if not for use really and private. To publicly reproduce an image produced by others, it takes the permission of the author, which authorizes the use of the image signing or an authorization or a receipt of the remuneration gotten with the indication of the rights of use surrendered.

If there is not therefore a to regulate permission, the exposure or the projection in public place (even if not for the sake of money) of images produced by third, they is considered violation of the right of author.

The same discourse is worth for the use of the images on Internet, compared to the other means of diffusion of the information. The right of author can be ownership both of the author same that of possible heirs and it has a 70 year-old temporal duration. Mistake such period the image becomes of public dominion and you/he/she can freely be used.
