"Single Topic" version

Get the code here: https://gist.github.com/ninjastic/59bde80306c32153a5775b9a570b16b7

Run it on any topic and all images posted by you will be updated.

IMPORTANT: only images that are shown on the screen! This means that if you are on page 1, the script won't update the images on page 2. You can use the ;all page on the forum to make all posts show up all at once (probably won't work properly if the topic is huge?).
