A couple of the computers I use have limited RAM (4 GiB), and Chrome and Firefox use up a lot of memory. So, sometimes I don't want to fire up an entire separate web browser, and since I'm almost always in Emacs anyway, I just use the Emacs Web Wowser, the web browser written in Emacs Lisp.

EWW, the Emacs Web Wowser

Here are the functions I use to switch Emacs to using EWW by default to open URLs:

(defun tkb-browse-url-eww (url &optional args)
  "Invoke the eww browser (inside emacs) on URL.  It the optional second
argument ARGS is true open in a new buffer."
  (message "args: %S" args)
  (eww url (and args 4)))

(defun tkb-toggle-eww ()
  (cond ((eq browse-url-browser-function 'browse-url-default-browser)
         (message "Switching to EWW for opening URLs.")
         (setq browse-url-browser-function #'tkb-browse-url-eww))
         (message "Switching to browser-url-default-browser for opening URLs.")
         (setq browse-url-browser-function #'browse-url-default-browser))))

You could do something similar using w3m.el, which uses the external text mode web browser w3m to render the HTML, but that doesn't (as far as I know) support images, and EWW does.
