I’ve been using WordPress for this site for about 6 years and am generally quite happy with the fact that it “just works”. I’ve been using a simple default theme (Twenty Twelve) for much of that time as well. Recently I’ve been trying to be a bit more active on the blog and there are few (very minor) issues and personal taste differences I have with the theme which I’ve hacked out it of it.
I was doing some reading on how best to integrate SmugMug with the site since I’m on the verge of switching from Flickr for my personal photos and while I was doing this reading I discovered that there is a correct way of modifying themes for WP! It’s actually quite elegant and avoids several potential problems.
I give you WordPress Child Themes.
