According to the debate, they had their reasons. But still -- when one hundred and eighty six nations say one thing, and two say another, you have to wonder about the two.
But you can to imgur, grab the direct image URL and then embed it as such:
![alt text - optional](URL)
And to make a button:
[![alt text - optional](image URL)](on-click destination URL)
Example:
In this case the image is just 0.9kB, so to save an unnecessary request to Imgur, I used data URI with base64. You can't do this with larger images due to comment size limitations. Just imagine a normal URL in there.
The whole images database debacle with Lemmy is kind of a big deal, and I have never seen an announcement about it, but I'm on team turning it off on a small instance like blahaj.zone. It's too much data and this instance is too small to afford that kind of server space. Plus, unless things have changed, there is basically no real server panel for controlling the image database and admins basically have to manage it manually. Which is something that is pretty daunting for some admins.
So yeah, fuck the image support, use imgur, if you're a blahaj user.
