I need opinions on a (possibly) new Kbin-it version!!!

Basically I just made something related to images. (My post about it, the instance is blocking the embed so open it in a new tab instead)

I played with it for half an hour and somewhat made it display inside the post instead (like new reddit and social media posts).

• Long images still display really small, so you need to open the thread to see it fully. That's how a long image looks like
• It doesn't work on embeds (imgur posts NOT imgur images, articles, mastodon posts) yet, I will try to find a way to make them work with it
