I am trying to replicate the way in which images in the feed on this website (http://haw-lin.com/) are bottom-aligned.

From copying and tinkering with the code on the site, I conclude that the bottom alignment is not being achieved through pure CSS—at least not evidently through the use of linked style sheets as opposed to inline style definitions. I determined this by commenting out all the linked style sheets; many other aspects of the site appeared wonky when I did this, but the bottom alignment of the images was not broken. The images only began top aligning relative to each other when I commented out included javascript files or sections of js code.

Any help in diagnosing what specifically is making the bottom alignment of images on this site possible and/or advice on how to similarly implement this effect on my site would be greatly appreciated.
