Can I ask the images and repeating the alt pagetitle the page title?

On the page there are ten images in the article. If they all set pagetitle and alt, repeats the page title? — You know, you can, but whether it is right or wrong? I know it's not right, but sometimes just too lazy to register these titles, and now the choice falls on two options (more on those below).
The question probably should be:
Is there any reliable information about the impact on the ranking page duplicate metadata from different photos and if you choose from two options — a) to prescribe the same everywhere, the headers of all the images of the article and b) it is better not to prescribe, what should prefer and why?
Common conjectures, arguments, ideas are welcome.

Option a) effect on entry, it is better that they were because of the 10 keys to alt-Ah is unlikely to be perespa.
