I was wondering what most authors use to power their galleries for their themes. Do most of you use the default WP gallery shortcode? I’ve been trying to style the default WP gallery for my theme, but the images aren’t resized correctly, making the spacing look really bad on the actual gallery page. Does anybody know how I can automatically resize these images depending on the number of columns selected by the user in the shortcode? I just ask this because in my previous themes I had a lot of complains that the default WP gallery didn’t work so I’m trying to fix it for my next release.
