Nice, the last version was crashing badly for me.
I have a couple more 'simple' suggestions:
I think the words are kinda hard to read in the comments, like they are a bit dimmed, I use an automatic theme switch, so I think this is more noticeable with the light theme (though they are dimmed in dark mode too).
Can we have a way to show the title of the post on the top of the images? A switch for this might be good as well.
