The original Album Theme only appears to allow for images that are 600 by 400 pixels; in other words, you get what’s traditionally called “landscape” view only. Not all my images are done in landscape format. In particular, many people shots will be in “portrait” view — maybe that’s why it’s called “portrait” view.
This is a test post to see if the PHP tweaks I’ve made to the theme work. If they do, I should have a proper portrait view image, with a wider area for the blog text.
