really I'm putting this here for my own reference as much as anything

Dear tumblr-using internet:

Consider inserting this into your layout (somewhere within the style tags):

blockquote img {
max-width: 100%;
height: auto;}

img {
max-width: 100%;
height: auto;}

Yes, any images embedded into reblogged text posts will shrink, but this makes it so they're shrunk in proportion rather than being all squashed (or remaining at their full size, and breaking everything).

Yours,
Van
