So far I've captured 51 screenshots showing the development of thisis from absolutely nothing at all to something nearly usable.
I want to be able to display these screenshots as full screen, with previous and next links and the caption overlaid and the description below.

Since the screenshots are already "complete" then they don't need the header / footer
I need to create an attachment.html template.

Requirements

• Ability to display screenshots which have been uploaded as attachments.
• With a caption and/or description
• And previous and next links
• And maybe an archive or page to display all the screenshot attachments.

Proposed solution

• Create an attachment.html template
• Find a way of displaying the actual image for the post being displayed.
  • Crib the solution from genesis-image
  • OR use an oik shortcode.
