Hello Timo,
thank you very much for the explanation regarding CSS. Then it’s not the root of my problem! By the way, who is Tim? I haven’t got his message. The error symbol in my screenshot is appears NOT for certain types. Some jpg’s show perfecty up, but most are shown as errors. This goes for png and others as well. Yes. Every wiki link to a picture of Ryazan on this page (https://en.wikipedia.org/wiki/File:Old_map_of_Ryazan.jpg) doesn’t work for me. An error “Too many requests - 47f834a351bd” comes out: If you report this error to the Wikimedia System Administrators, please include the details below. Request served via cp5030 cp5030, Varnish XID 514771340 Upstream caches: cp5030 int Error: 429, Too many requests - 47f834a351bd at Fri, 27 Jun 2025 05:27:01 GMT But the link to the source works perfectly well. And your link: https://upload.wikimedia.org/wikipedia/commons/thumb/b/b7/Old_map_of_Ryazan.jpg/500px-Old_map_of_Ryazan.jpg works for me fine as well. On the Supermium, that is overloading my system, I can see all wiki pages perfectly, with all pictures and maps intact. And on Firefox 52 and 68 not. So the problem is not with WinXP, it’s somewhere between the old versions of Firefox and Wikipedia. Thanks and kind regards!

Wikipedia is not actively blocking the use of my browser. Its CSS seems to have been changed so the pictures and maps do not show up. So back to my question: can I do something in my side, except for changing the system or the browser, to see the pictures and maps again? […] The error symbol in place of the images means that CSS is not relevant here. CSS is robust and protected against unknown rules. It's very rare that a CSS issue could cause an image to be hidden. The only way that CSS will hide an image, is if a developer intentionally applies a rule like opacity 0, display none, or visibility hidden. This could in theory be done as part of an animation, and perhaps the second part of such animation is unsupported, in which case it could remain hidden. This would be in our control to fix. However, if this was the case, the place where the image goes would be blank, not display the "broken image" symbol that you see. As Tim points out, this symbol seems to only be there in your screenshot for certain image image types and not others (JPEG vs PNG). That further confirms there is no styling issue as that would apply to all image thumbnails equally. Did you try opening it in a new tab? For example, open this link: https://upload.wikimedia.org/wikipedia/commons/thumb/b/b7/Old_map_of_Ryazan.jpg/500px-Old_map_of_Ryazan.jpg This is a direct image URL. There is no HTML, CSS or JavaScript in our control when viewing this. If the image fails there, then there is most likely something defect in the browser or operating system. If you really want to rule it out further, I suggest to download ("save as") the JPEG image from this exact URL on someone else's computer, and send it to yourself / to this computer (perhaps by email) and then drag it into a new Firefox tab / empty browser window to view it. Does it work there? If that works, but the same image by URL does not, then we can revisit if there's something else going on. -- Timo
