# mode
#
# In-set HTML photo modes. If you turn this on, tags will be
# placed in each item's description. Options for this are:
#
# basic - no images at all
# highlight - only the highlighted image
# thumbs - all thumbnails
# thumbs-with-captions - all thumbnails AND captions for each
# mdm - the mystery option!
#
# Note that this setting has no effect on the photo and pb elements,
# discussed above. Also note that 'thumbs' and 'thumbs-with-captions'
# have been known to crash NetNewsWire.
$mode = "basic";
# highlightAlbum
#
# Which album's highlight picture should be the highlight for the
# whole RSS feed? If set to '*' it will select the highlight image
# of the most-recently-created album.
#
# If set to "", it will turn off the channel highlight feature.
# (See noBigPhoto below for more info).
$highlightAlbum = "*";
# onlyFindable
#
# Suppose you have an album with 5 sub-albums, and you don't want
# anyone to look at any of them, so you mark the big album as
# hidden. Technically, users can still look at the sub-albums, but
# they can't actually _find_ them.
#
# Given that definition of findable, turn this off if you want
# only finadable albums to be visible.

# noPhotoTag
#
# There are two RSS extensions that allow for images representing
# items to be linked from feeds. They are:
#
# From Pheed Spec (see http://www.pheed.com/pheed/):
# photo:imgsrc and photo:thumbnail
#
# From PhotoBlog Spec (see http://snaplog.com/backend/PhotoBlog.html):
# pb:thumb
#
# These elements shouldn't be damaging at all, even to clients
# unaware of their meaning, but if you want to turn them off, you can.
$noPhotoTag = FALSE;
# noDCDate
#
# Having both pubDate and dc:date elements for an item may cause it
# to not validate. If you absolutely MUST have strictly valid RSS,
# set this option to TRUE. However, doing this may break some older
# RSS readers that don't fully support RSS 2.0.
$noDCDate = FALSE;
# noBigPhotos
#
# The whole channel can have one highlight image, but it can be no
# more than 144 pixels wide and 400 pixels tall. Since most galleries
# have thumbnails 150 pixels wide (for landscape photos), a small
# amount of clipping may occur on some clients. So most people won't
# really even notice, we lie about the sizes if the thumbnail is too
# big.
#
# If some clients complain that the channel thumbnail is garbled
# in their news reader because of the bogus size, you can set this to
# false to turn that feature off, but it will cause your RSS feed
# to not validate.
