Thank you very much to the executive. The goal is at the moment achieved, even if not by these tools. I didn’t even need a special utility. Sergey just pointed out what I needed and introduced two examples of the software that solves my problem. You can choose whether paid or not. The main thing he called things with his names - I just didn't know what I was looking for. In addition, I submitted a tool in Excel that will help in this problem and in others and will save a lot of time, because in this program I understand a little - all the method of running.
I strongly recommend this freelancer. Thanks for the help again.

As a positive person
We did more than we discussed.

Sergey advised well on all the nuances of JS performing the task. The result is on the screenshot. Additionally, he suggested how (css, less) the image is drawn out in the slider on the main (screenshot No. 2). Replacing it was easier. I have given a SEO website. Only positive emotions from cooperation, I recommend it to everyone!

A very comprehensive seash. He optimized the site by solving the "slip", which a few specialists who were addressed could not eliminate. I will address myself now. I recommend to everyone.

I remained satisfied. Live conversation, a person can be said help almost a gift (;
