But let's say it was using kind 20 only, I guess this would represent exactly what I intended to do with gallery entry events. Basically images you want to share and put in your profile gallery, and not every screenshot from every shitpost. It's a bit redundant to have 2 kinds for the same thing, I think. Just the way you create these currently in Amethyst is a bit different than actively posting a kind 20 event, like this client does. But it could be similar.

Kind 20 is for all the shitposts, all memes and things you want to share but might not want in your Gallery. To me they are very different.

Hello. Is a kind 20 for instagram style image posts, where my intention is kind of creating a public gallery of aesthetic images? Vs attaching a meme or something contextual to a text note, like I would in an Amethyst post. Thanks.

It is to post whatever you want as image, like memes and so on. It doesn't need to be for your own gallery.
