Met with PAB and made a number of fixes:

• Created a new copy of all the images in a folder called displaysize, and resized some of them to comply with owners' requests; the webapp now draws from that folder.
• Made changes to menu captions, and added a new menu item and placeholder page for it ("In progress").
• Removed authentication by commenting the relevant bits of the webapp's web.xml file, and restarting the webapp in the Tomcat manager. The Tomcat config still has the user set up, but it's no longer being used for anything.
• Fixed a couple of layout bugs.

We also made a plan for an advanced search, which I'll document in more detail here before I try to implement it.
