Answer 1

These characters are similar to Cyrillic.
Let's say that you have a link:
s14-group.ru/design/razrabotka-logotipov/
It has a picture of Design-logo.jpg, but because of this name it is displayed as:
/%D0%A0%D0%B0%D0 %B7%D1%80%D0%B0%D0%B1%D0%BE%D1%82%D0%BA%D0%B0-%D0%BB%D0%BE%D0%B3%D0%BE%D1% 82%D0%B8%D0%BF%D0%B0.jpg
By the way, all your pictures seem to be written in Russian, and when clicked they open separately.
The crime has been solved.
