JT provided two new maps for the gallery, so I've added those. I had to refresh myself on the procedure for doing this, so I'll detail it here:

• Extract the bitmaps from the PDFs (if that's the format they come in) using pdfimages -j [pdffile] [outputprefix].
• Create meaningful filenames based on repo, id numbers, and year.
• Copy the full-sized originals into the correct year in [coldesp]/maps] on local drive. These will just be backed up locally.
• Create a quarter-sized "large" image (max width 5000) in maps_lg.
• Create a 1000px-wide version in maps_1000.
• Create a 200px-wide version in maps_200.
• Create a 100px-wide version in maps_thumb.
• Create an XML file with the same name as the image file, and a matching @xml:id. It's simplest to model this on an existing file. Save it in xml/maps.
• Fill out the metadata, and point the facsimile graphic at the right file name, with the right dimensions.
• Add the XML file to SVN and commit it.
• Upload the images to home1t, and the XML file into the db.
• Test to make sure the map shows up in the gallery, and works properly on the site.
