Writing articles for the site is a serious and responsible matter, because the text should be interesting, literate, readable and unique. And to increase the interest of visitors to the materials published on the pages of the resource can be with the help of illustrations that will give the appearance of the article attractiveness.
Drawings, images and photos published on the site have the same requirements as texts - they must be unique.
A unique picture is a graphic image that exists in a single copy and has not been published on the Internet on any resources before.
It should be noted that placed on the pages of the web project unique images with a filled in title (Alt tag) contribute to increased traffic and improve the position of the site in the search results of Yandex and Google.
As a rule, webmasters do not bother to order, buy or draw illustrations themselves, but simply find and download them from the Internet.
In order for the downloaded images to be placed on the site you need to do some serious work on them.
Using any graphic editor to make the picture unique,
you need to perform any four actions from the list below:1. Saving the file under a different name.
2. Resize the image.
3. Pruning.
4. Mirror horizontally or vertically.
5. Change the brightness (shutter speed).
6. Increase contrast (clarity).
7. Adding text.
8. Retouching.
9. A collage of several illustrations.
10. Convert to another format.
However, these manipulations do not always yield positive results, nor do they make the image unique.
Search engine robots have now been taught to process, "understand" and enter into their databases information about all graphic images published on web pages.
Therefore, before placing a processed image on your website you should check it for uniqueness.
