Freeze when loading images from OSM Weekly

[Karry]

Hi. When I open article from this rss feed: https://www.weeklyosm.eu/cz/feed and load article images, Tidings freeze completely.

[Karry]

Well, it doesn't freeze forever, but for very long time - 20 seconds. From the stacktrace during that freeze, it seems to me that it is not caused by the tidings itself...
