Detail- and original images are not displayed

I have this problem!

I have read this:

"The reason for this is usually a conflict with a system plugin in Joomla!. That doesn't mean those with Joomla! supplied system plugins (core) are meant, but which are installed by a third-party extension.

To determine the problematic plugin, deactivate the third-party system plugins for testing purposes and check whether the detailed / original images are displayed then."

I have 104 system plugs in. How do I easily evaluate which one is causing the problem?

Do you have a "black list"?

So I found the culprit on my website. Regular Labs - Rereplacer plugin does it. Reproducible turning on and off. Have informed them today. May be there will be a fix.
