       igal2 - online Image GALlery generator


       igal2 [-option1 -option2 ...]


       igal2  is  a  quick and easy program for placing your images online with just one command-
       line invocation.  It generates a pretty  good-looking  set  of  W3-compliant  static  HTML
       slides  even  with its default settings.  To try it out just run igal2 in a directory with
       jpg, gif or png files and check  the  output  in  a  web  browser.   You  can  adjust  the
       appearance  of  the image gallery with the many options listed below or (if you know a bit
       of HTML) by modifying the .indextemplate.html,  .slidetemplate.html  and  igal2.css  files
       that  igal2  creates  in  your  image directory.  igal2 also checks for the existence of a
       $HOME/.igal2 directory where users can store their own templates, overriding the site-wide

       igal2 needs Perl to run and it also relies on a few other programs that come standard with
       most Linux distributions.  It relies  on  the  ImageMagick  package  first  if  available,
       otherwise  it  falls back onto cjpeg/djpeg/pnmscale for processing jpg files.  The command
       convert of the ImageMagick package is required to  process  gif  and  png  files  and  the
       identify  command  enables  igal2  to  include  IMG  HEIGHT  and WIDTH tags in the HTML it
       generates.  If you would like  to  show  the  EXIF  headers  of  the  images  (option  -e)
       Image::ExifTools is needed.


       -a     Write image dimensions and sizes under each thumbnail on the index page.  This only
              works if the ImageMagick command identify is present.

       --ad   Like -a but write only the image dimensions.

       --as   Like -a but write only the image sizes.

       --bigy <n>
              Like -y but operates on the image slides, not the thumbnails.  Scales image  slides
              to  some  medium  height (e.g.  400), adjusting their width accordingly.  Useful if
              your digital camera spits out large images, like 1600x1200.  The  originals  aren't
              affected,  but  scaled  copies of your images are stored with the .slide prefix and
              thumbnails link to these copies.  Clicking on the scaled copies in the HTML  slides
              lets  users  see the full unscaled images.  You must use -f between two consecutive
              runs when you've changed the value of --bigy.

       -c     First generate and then publish image slide captions. The first invocation of igal2
              -c  generates  a .captions file that you may edit.  The format of this file is very
              simple.  You should only have to enter your captions after the ---- separator.  You
              may  rearrange  the  image  order at this point and also leave out some pictures by
              simply placing a pound (#) sign at the beginning  of  their  respective  lines.   A
              second  invocation of igal2 -c will read your .captions file, include your captions
              in the slides and rearrange them if necessary.

       -C     Like -c but preserve file names as captions  when  generating  the  .captions  file
              (strips file name suffix).

       --con options
              Command  line  options  to  pass  on  to convert or cjpeg internally (see their man
              pages).  This affects all thumbnails and,  if  --bigy  is  given,  the  medium-size
              slides  too.  You can set the -quality or go crazy with -negate, -noise, etc.  (the
              last two only work with convert if ImageMagick is installed.

       -d <dir>
              Operate on image files in directory  <dir>,  which  is  also  where  the  HTML  and
              thumbnail files will be generated.  The default is the current directory.

       -e     Extract  all  EXIF tags from the images and display them on the image slides.  This
              option needs Image::ExifTool to be installed.

       -f     Force thumbnail regeneration.  Also forces medium-slide regeneration if  --bigy  is
              given.   Otherwise igal2 will not regenerate these files if they already exist, and
              you may end up with stale copies.  Definitely use -f between two runs where  you've
              changed the value of --bigy or --con.

       -h     Display brief help, same as --help.

       --help Display brief help, same as -h.

       -i <file>
              Name of the main thumbnail index file.  The default is index.html, as desirable for
              most web servers.

       -k     Use the image captions for the HTML slide titles.  The default behavior is  to  use
              the image names.

       -m <watermarkfile>
              Add  a  watermark to each file. The parameter specified is another image file which
              will be overlayed in the top left of the image with some transparency applied. This
              option  requires  ImageMagick.  The  original  images  will be left in place with a
              '.unmarked' extension. You may wish to delete those afterwards. If this  option  is
              specified on two consecutive runs, igal2 will detect the .unmarked versions and not
              run it through the watermarking process again. Transparent GIF files work well  for
              this option.

       -n     Use  the image file names for the HTML slide files.  Otherwise the default behavior
              is to simply name your slides 1.html, 2.html, and so on.

       -o <URL>
              Use this option if you are hosting the index files in a different location (e.g.  a
              different  server)  from the back end images/slides. This option adds the specified
              prefix into the URLs of the slides. If you use this option, remember that until you
              move the files into the resulting location, the gallery won't work properly.

       -p <n> The cellpadding value of the thumbnail index tables.  The default is 3.

       -r     Omit  the  film  reel  effect  altogether.  For a simpler look you can also set the
              thumbnail background to be the same as the main index page background with the tile
              background-color option in the igal2.css file.

       -s     For  the simplest setup, omit all HTML slides.  Clicking the thumbnails on the main
              page will just take users to the plain image files.

       -t <n> Height (in pixels) of the tiled image used to simulate the  top  and  bottom  "film
              reel"  effect  on  the  thumbnail index page.  This is 21 for the default .tile.png
              image used, but you should set it otherwise if you replace that file with your  own

       -u     Write  image  captions  under  each  thumbnail  on  the  index page.  If you have a
              .captions file (see options -c or -C) then the captions are read from  there,  else
              the file names are used (but the file extension is stripped).

       --pagination <n>
              Maximum  number  of images on one page.  If the given number of images is reached a
              new page is started. Pagination number n should  be  a  multiple  of  parameter  -w
              (default 5).  Default 0 - means no pagination at all.

       -w <n> Set the thumbnail rows to be <n> images wide in the main index file.  Default is 5.

       -x     Omit the image count from the captions.

       -y <n> Scale all thumbnails to the same height of <n> pixels.  The default is 75 pixels.

       --xy <n>
              Scale thumbnails to <n> pixels along their longest dimension.  This value is passed
              to pnmscale and only works properly for jpg images.

       --www  Make all igal2 files world-readable.

       --dest <dir>
              Per default igal2 places all igal2 helper files (thumbnails, slidefiles, CSS,  etc)
              in the directory where the image files reside.  With this option these files can be
              placed in a subdirectory of the image directory.

              If igal2 finds subdirectories below your image directory it will add links to  this
              directories  in  the  index.html  file.  This  is  useful if you've a tree of image

               + Vacation_Vienna (Image Directory)
                 + .igal2-stuff (igal2 helper files)
                 + Videos
                 + Documents_of_interest

               igal2 -d Vacation_Vienna --dest .igal2-stuff --AddSubdir

              will put all helper files in .igal2-stuff, and generate links to the subdirectories
              "Videos" and "Documents_of_interest" in the index.html file.

              Note:  igal2  will  not  work  recursively,  it  just  adds HREF links to the found


              The default index template file.
              The default file used to generate slides.
              The default style sheet template.
              The tiled image used for the "film reel" effect.
              The default file used to generate directory links in index.html. If  this  file  is
              changed, the index.html has to be regenerated by running igal2 again.
       All  five  files  are  copied  to  your image directory as dotfiles the first time you run
       igal2.  Modify the local copies (but keep their names) if you need to  further  alter  the
       appearance  of  your  slide  show (also see -t).  igal2 also checks for the existence of a
       $HOME/.igal2 directory where users can store their own templates, overriding the site-wide


       Run  igal2  in a directory with jpg or gif images to see what it does.  Then play with the
       options  described  above  and  use  -h  if  you  need  a   quick   listing.    Also   see for online examples.


       There  are  always  some.   If  you  find any let me know.  I don't have much time to keep
       tweaking igal2 but if any major bugs pop up I probably ought to fix them.
