I have that Chrome extension and a similar one for Safari.
I just dislike opening images inline or all loaded into one separate tab, because then it turns saving individual images into a mouse-driven task rather than a keyboard-driven task.
As an aside: what do you use to browse Hacker News on your phone?
There are some apps for browsing HN in the app store, but I haven't bought any of them to try. Right now I browse HN through http://ihackernews.com/ which is a nicer stylesheet for mobile browsing.
