Havent thought of that; yes, this communities’ instance uses Lemmy in a small version before this feature (nothing bad in it otherwise, I know firsthand updating this can be a pain). Yours is lagging even more btw, current version is 0.19.8, you can log in to lemmy.ml or any other fully up to date one to check if that changes anything important for you. Otherwise its not a major issue.

So yeah, leaving either the pic or the link in the body might be the best there is to be done for now.
