removing the border update on images:
you'll need to use the stylus extension (chrome, firefox, opera, github), on mobile you can use this extension on firefox (extensions are not available on ios afaik)
create a style:
set it to work on all sites under the tumblr domain:
copy paste this code:
.GzjsW .CQmeg.lN9Zs.T94I2 > button:after, .GzjsW .CQmeg.lN9Zs.T94I2 > div > button:after, .GzjsW .CQmeg.lN9Zs.T94I2 > figure > div:after { border: none;}
that should be it, now transparent images should no longer have the ugly border.
however, please note that:
this does not remove the rounded border from solid images
this does not remove the color of the post background changing on hover.
this may stop working if tumblr changes things in the future. please don't send me abusive messages about it.
very quick edit:
i figured out how to stop the hovering change in bg color
add this to the same style:
:root { --content-tint: rgba(0, 0, 0, 0)!important; --content-tint-strong: rgba(0, 0, 0, 0)!important; --content-tint-heavy: rgba(0, 0, 0, 0)!important;}
