This was closed as Done, but the issue is not fixed.

There is still way too much space filled with useless images. Just two feedback tracker links fill my whole screen space, and 42% of the space, is images that provide no value.

GitHub is similarly bad (A bit smaller though), but at least their images provide somewhat useful information (Who created it, when, their avatar, how many comments)

Gitlab is nice and compact

The important information to be seen is the issue title, thats what we need in the embed.
A bit of the description can also be useful, but everything else is just wasteful, and makes people want to turn off embeds, which means information isn't visible at all.

I try to post a changelog, and my whole screen gets filled with this.. So I end up having to disable the link embeds completely.

If you could just make that image be a thumbnail (like the GitLab one above), that would already help.
