* Show the content on the page (the text in 'Description')
* Use an aside instead of a div as wrapper for the attachment info
* Only show the gallery when there are attachments to show
* Order the images under 'gallery' randomly
pages. Attachment pages show images that are attachted to the same
parent post as the current image. If a unattached image is shown, it
displays all other unattached images. That number could be very high so
it has been limited to 20.
