• Lossless Derivative Creation?: Enabling this will force the Large Image Solution Pack to use no reversible lossless compression when creating JP2 derivatives.  When a JP2 original is uploaded, a second "use" copy is created for the JP2 datastream.
• Use Kakadu for Image Compression?: The Kakadu software suite can be installed on your server to take advantage of its much faster kdu_compress program. Check  Users often use the copy of kdu_compress that comes bundled with Djatoka (see below), but you can also check out the official website at http://www.kakadusoftware.com/ for download and installation instructions.

Configure the image-tool kit to use ImageMagick rather than GD in Administration > Configuration > Media > Image Toolkit (admin/config/media/image-toolkit). If GD is selected, TN and JPG datastreams will not be generated.

...

Select configuration options and viewer in Administration > Islandora > Solution pack configuration > Large Image Collection (admin/islandora/solution_pack_config/large_image).

To use Kakadu, make sure that kdu_compress and kdu_expand are avaliable to the Apache user. Often users will create symbolic links from /usr/local/bin/kdu_compress to their installation of Kakadu that comes bundled with Adore-Djatoka. Make sure that the required dynamic libriraries that come with Kakadu are excessible accessible to kdu_compress and kdu_expand. If they are not present, attempting to run either command from the terminal will inform you it's libraries are missing. You can also use a symbolic link from /usr/local/lib to include these libraries, remember to restart the terminal so your changes take affect. Also, make sure the php settings allow for enough memory and upload size: upload_max_filesize, post_max_size and memory_limit.
