How to use photos taken from Yandex. Pictures and similar places?

Question

Copyright

When creating your first work for a web development portfolio, you had to use photos from Yandex. on photo stocks the necessary pictures were not possible. But some of the photos have a link to a site where the author is listed. And so the following questions arose:

• Is it possible to use photos from Yandex.Images
  
• If possible, is it required to indicate the author and contact him to use his photo (even if there is no watermark on the photo)
  

An example of using a photo on the site:

And here is a link to this photo: https: //yandex.ru/images/search ?pos=4&img_url=http...

Answer 1

Let's start with the fact that the Yandex.Pictures service is an aggregator that, through bots and a script posted on the site, parses, including photos, with subsequent provision in search results. From your link, you can see that the photo was sparse from the site of the photo center dot ru, and in turn, the site at the bottom of the page spells out the basic conditions for the type:

Attention: All rights to the posted works belong to the authors It
is forbidden to use photos without their personal permission

As well as information located in the user agreement of the site:

4. Copyright
We are the owner of all copyrights in all information contained on the site, unless otherwise indicated.
Contributors submitting works to the site must be the full copyright owner of those works, or the owner of related rights, or have the official permission of the copyright owner, or have the rights in any other way permitted by law.

You agree not to use the information from our site (other than information posted directly by you) in any way other than as permitted in this user agreement. You agree not to interfere with the operation of our site, except when you receive permission to do so, or when using the services provided by us.

Therefore, these conditions posted on the site, as it were, let you understand (if you do not know) that the posted photos are protected by copyright and require written permission from the site owner or the author himself to use these photos. The only question is that if you post these photos on your resource without the consent of the author and these photos are found with a clear condition for their illegal placement, will you be subject to any measures to enforce these copyrights or simply "pass by" - that's another question.
As a result:
1) It is better not to use it without permission, given that information about this is directly indicated on the site;
2) The conditions for specifying the author must be clarified either from the author himself or from the owner of the site on which this photo is posted.
