if I export all my own posts from rapamycin.news forums, it only shows my forum posts a text, but not the images embedded in the thread of the text.
example thread: Short bursts of intense exercise (HIIT-adjacent)/how to measure them properly? - #11 by AlexKChen - Rapamycin Longevity News
I see you’ve posted a similar topic last year.
If you look at How to allow downloading images along with other user data (csv) from activity section?, there is a new cooked column in the user_activity.csv folder. It contains the HTML of your posts, where images are in <img> tags.
But it seems that this forum is running 2.9.0.beta9. That’s very old (about 4 years). It was released in July 2022, but this feature looks like it was added in November 2022. You’ll probably need to ask the admins to update the site.
