# Given a list of image file names, writes an HTML file that

# shows all those images, with optional one-line headers above each.

# Each "filename" can also be a list array of filenames (they will share a title).
|

|
# Strips directory information away if options.makeRelative == 1.

# Tries to convert absolute to relative paths if options.makeRelative == 2.
