I hate the way Mastodon handles images. Giving me an image preview with weird dimensions that cut off most of the picture is bad enough. That I don't automatically get the full image when I open the toot in a separate window is just bad UX.
@ink_slinger completely agree. the thumbnails are weirdly sized, and the lag to open the picture when clicked on is a bit frustrating.
@captainnapalm Yep. The lag might be an instance specific thing. But the thumbnail size is universal, and it's terrible.
