zannauvoak by default, the images actually do appear inline instead of stacked on top of each other, for example:
(FoF Formatting with AutoImage turned on and MediaEmbed turned off, so the links appear like actual images + cache clear)
Your forum probably has another extension/theme, or a custom CSS that overwrites how the images display in posts, but I can’t tell which one it is. I imagine that can be overwritten with another custom CSS to display images inline, but since I can’t reproduce this issue, I don’t know what CSS would fix it
