Requirements

IDS has been tested under Red Hat Linux 6.2, FreeBSD 4.2, OpenBSD 2.8, and Mac OS X with Apache 1.3.9-1.3.19, and Microsoft Windows 2000 with IIS 5.0, but may work under other OS's or webservers after some modifications.

Note that ImageMagick requires a sizable amount of RAM when it is manipulating images. The larger the images you manipulate, the more free RAM you will need. I recommend having at least 30MB of real memory free.

For best results, your server should have a relatively fast processor.

• a webserver capable of executing Perl CGI's (I recommend Apache)
• Perl 5.00503, 5.6, or 5.6.1
• ImageMagick 5.3.1 or later (w/ PerlMagick aka Image::Magick)
• the Image::Info Perl module
  
  For help installing Perl modules, please read the documentation available at CPAN.

• Microsoft IIS 5.0
• ActiveState ActivePerl 5.6.1 build 626 or later
• Image-Magick Perl module 5.3.1 or later
• IO-String Perl module
• Data-Dump Perl module
• Image::Info Perl module
• jpegtran.exe (optional- allows JPEG's to be rotated losslessly)
  
  Many common Perl modules are available through Perl Package Manager. If not, they can be compiled using source from CPAN.
  
  The current Image-Magick Perl module available through PPM does not work. In order to use IDS, ImageMagick version 5.3.1 or later is needed. Download the latest version, and follow the instructions to compile the Windows 2000 ImageMagick and PerlMagick source.
