Wordpress doesn't show images in popups

Question

CMS

The other day I noticed a problem on one of the blogs (more precisely, the girl whose blog this was noticed). On it, pictures are loaded from the liveinternet site (the beginning of the link img0.liveinternet.ru/images/foto/... ), so as not to waste paid space.
And so, the problem is: if the picture is located on the wordpress site, then it opens normally (pop-up window), if on another site, the file itself opens. If you open a picture from the site at the beginning, then when you switch, the rest are displayed in a pop-up window.
There was a Lightbox Plus plugin. Checked plugins Shutter Reloaded, Auto Thickbox, FancyBox for WordPress, jQuery Colorbox, all have the same problem.
Maybe someone faced a similar problem and was able to solve it?

Answer 1

I solved the problem. If you are interested, the problem was in the All in One SEO Pack plugin or in Google Analyticator (both have the same functions for Google Analytics), when using "Tracking outgoing links", to fix it, you need to disable this option.

Answer 2

Have you thought about the fact that pictures are simply glare to open them from other sites?
Something like this: Quite a normal practice.
valid_referers none blocked server_names *.liveinternet.ru;
if ($invalid_referer) {
return 403;
}
