Raw text without reaction images is sad so here's an add-on to display linked images with Tampermonkey.
// ==UserScript==
// @name Fetch images from url
// @namespace http://textboard.org
// @description Replaces links to images with the actual image
// @include *
// ==/UserScript==
(function() {
function getXPath(p, context) {
var arr = new Array();
var xpr = document.evaluate(p,context,null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null);
var item;
for(var i = 0;item = xpr.snapshotItem(i); i++) {
arr.push(item);
}
return arr;
}
var doc = window.document;
var xpath = "//A[(contains(@href, '.jpg') or contains(@href, '.jpeg') or contains(@href, '.gif') or contains(@href, '.png'))]";
var results = getXPath(xpath, doc);
for(var i = 0; i < results.length; i++) {
var img = document.createElement("img");
var source = results[i].getAttribute("href");
img.setAttribute("src", source);
results[i].textContent = "";
results[i].appendChild(img);
}
}
)();

It could be improved to position the image on the top left corner, generate clickable thumbnails and display multiple images the way 2ch.hk does it.
