The discussion revolves around an issue with images in posts being too wide when “max image width” is set. tohaitrieu reported that images in their posts were overflowing, particularly when quoting long content from another article. codinghorror initially couldn’t reproduce the problem and suggested that the issue might be related to custom CSS.
tohaitrieu discovered that the issue occurred when quoting long content and suspected it was related to the Quote BB Code. After trying various solutions, including removing plugins and theme components, tohaitrieu added custom CSS to fix the problem.
Upon further investigation, tohaitrieu found that the issue was due to a difference in CSS between their site and Discourse. Their site had a max-width of 1200px, while Discourse had a max-width of 690px. tohaitrieu ultimately fixed the issue by changing the value to the default setting.
