Twitter: Hide images on timeline

Added by mildmojo@userstyles, Created: Oct 28, 2013, Updated: Oct 13, 2016

Description:

Twitter.com started showing images, videos, cards, and sales forms inline in your feed. There's no option to turn it off. This style restores the old click-to-expand behavior for tweeted images, videos, and cards. It also unhides now-invisible media links (e.g. pic.twitter.com).

Quoted tweets are displayed inline, but quoted images are hidden. Click the parent tweet to expand and reveal the quoted image.

Someday, this may break. Someday, I may fix it. It works for me as of the last update date.

NOTE: The morning of 2016-02-02, Twitter removed "click to expand" in favor of terrible modal popups. This style still hides images, but now you have to deal with dog-slow, ugly popups. =( Sorry, all.
