Those of you who visit this site on your phones will be happy to see that I’ve fixed the problem where large images were being resized horizontally to fit on the screen, but not vertically. It adjusts both the width and height together now, so large images shouldn’t look squished anymore!
Tested on the Android Browser and Opera Mini, and tested in principle on desktop versions of Chrome, Firefox and Opera, so it should work on Safari/iPhone as well. (Mobile Internet Explorer doesn’t support the feature I was using, so it shouldn’t have been affected to begin with.)
