Don't like it when chat is flooded with ponies? Too lazy to burn them all? You need PONIES: Protect Oneboxed Nuisance Images Everywhere Safely.

enter image description here

All oneboxed images are displayed with 0.1 opacity until you mouse over them.

Get the Chrome Extension

Simply download it and drag it into your Extensions page to install (you can drag directly from the download bar).

If you wish to use the styles raw with Stylish, here they are:

    opacity: 0.1;
    transition: opacity 0.3s;
    -webkit-transition: opacity 0.3s;
    opacity: 1.0;
    transition: opacity 0.3s;
    -webkit-transition: opacity 0.3s;

Check out my userstyle version that does essentially the same (use with stylish stylus or adapt into a userscript):

/* SE chat − safe for work image oneboxes */

@namespace url(http://www.w3.org/1999/xhtml);
@-moz-document domain("chat.stackexchange.com") {
  .ob-image, .ob-youtube {opacity: 0.1 !important;}
  .ob-image:hover, .ob-youtube:hover {opacity: 1 !important;}
  • This is a userstyle, not a userscript Jun 15, 2016 at 14:14
