There seems to be a common problem with the gallery and slider plugin. For some reason, it skips the second photo when I expand the gallery. It doesn’t like the photo, or something, but it’s ok on the page. There are a couple of other photos that do the same thing.

Even though the photo of the bird is first in the list of photos for the slider, the slider skips the bird photo and then it shows it later.
