You simply copy some gif's/jpeg's to a directory, create an optional text block (in a file called caption.txt) to go at the top, and the module does the rest. It does however require that PerlMagick be installed. Default settings in the srm.conf file may be overriden by creating a .htaccess file in the same directory as the image files and the caption.txt file. INSTALLATION perl Makefile.PL make make install (no test necessary) DESCRIPTION This module sets up a virtual set of photo albums starting at the `Location' definition. This virtual directory is mapped to a physical directory under `AlbumDir'. Under `AlbumDir' create a sub-directory for each photo album, and copy image files into each subdirectory. You must also make the permissions for each subdirectory so that the id which runs Apache can write to the directory. At this point, if you have PerlMagick installed, you can go to *http://your.site/albums/album_name* Apache::Album will create thumbnails for each of the images, write the caption.txt file along with the thumbnails to the client's browser. The thumbnails are links to the full sized images. The caption.txt file The caption.txt file consists of two parts. The first part is text/html, that will be placed at the top of the html document. The second part of the file is a mapping of filenames to captions. The module will do some simple mangling of the image file names to create the caption. But if it finds a mapping in the caption.txt file, that value is used instead. The value __END__ signifies the end of the first section and the beginning of the second. For example: Image -> Bob_and_Jenny.jpg Caption -> Bob and Jenny (the auto-generated caption) override in caption.txt Bob_and_Jenny.jpg: This is me with my sister Jenny. Here is a sample caption.txt file:

My Birthday Party

This is me at my Birthday Party!.
__END__ pieinface.gif: Here's me getting hit the face with a pie. john5.jpg: This is John ThumbNail Types `ThumbNailUse' can either be set to "width" or "aspect". If `ThumbNailUse' is set to "width", thumbnails that need to be created will be `ThumbNailWidth' wide, and the height will be modified to keep the same aspect as the original image. If `ThumNailUse' is set to "aspect", thumbnails that need to be created will be transformed by the value of `ThumbNailAspect'. `ThumbNailAspect' can be either a floating point number like 0.25 or it can be a ratio like 2 / 11. If an image file is updated, the corresponding thumbnail file will be updated the next time the page is accessed. In practice I have found that Netscape will used the cached images even if they are updated. I normally have to flush the cache and reload to see the new images. At any time you can `rm -f tn__*' in the `AlbumDir'/album_name/ directory, the next time the page is loaded all the thumbnails will be regenerated. (Naturally image names that start with tn__ should be renamed before placing them in the album directory. DefaultBrowserWidth A general number of how wide you want the final table to be, not an absolute number. If the next image would take it past this "invisible line", a new row is started. BodyArgs This entire string is passed in the tag. Useful for setting background images, background color, link colors, etc. If set in the srm.conf file, you must put quotes around the value, and escape any quotes in the value. If this value is set in the .htaccess file, this is not necessary: In srm.conf: PerlSetVar BodyArgs "BACKGROUND=gray.gif text=\"#FFFFFF\"" In .htaccess: PerlSetVar BodyArgs BACKGROUND=gray.gif text="#FFFFFF" OutsideTableBorder This variable's value is passed to the outer table's BORDER attribute. InsideTablesBorder This variables's value is passed to all the inner table's BORDER attributes. Note that the name of the `InnerTablesBorder' has an 's' in it, as it modifes all the inner tables. Footer This text/html will placed at the bottom of the page after all the thumbnails, but before the end of the page. Useful for links back to a home page, mailto: tag, etc. LIMITATIONS PerlMagick is a limiting factor. If PerlMagick can't load the image, no thumbnail will be created.
