Good day, thank you for your advice. I don't know how or why but after checking my PC by ccleaner, kasperksy's utility, malwarebytes. Now everything is good. I'll try to message to security-team next time if the problem happens again. Thanks!

Dear TGR, good day. I've installed the kaspersy secure connection. As I understand this programm supports some VPN. So as soon as I opened it I'm able to see the images. Do you know what that means? The problem appears only this site.

Thank you, I'll try to scan my PC for searching viruses, I think this is only way I can do.

It's really strange because though I have the kaspersky antivirus, firewall is on, but until recently it didn't bother me. Furthermore images were displayed in a some time. I tried to close the antivirus and others but it didn't work. But thank you, I thought this problem is in wikipedia site.
