The core install includes:Document Management
Content Platform and Repository
Content Management Interoperability Services (CMIS)
Collaboration (Share is a separate web application)
Web Content Management is multiple additional downloads. The core WCM functionality is enabled by downloading the WCM add-on (for Labs 3 Stable it would be called alfresco-labs-wcm-3Stable.zip). Unzip the file then copy the wcm-bootstrap-context.xml file to your Alfresco extension directory (could be $TOMCAT_HOME/shared/classes/alfresco/extension or $TOMCAT_HOME/webapps/alfresco/WEB-INF/classes/alfresco/extension).If you need to run the deployment process to copy WCM content out of the repository to some destination, you'll need to download the deployment app. For Labs 3 Stable it is called alfresco-labs-deployment-3Stable.zip.Records Management is packaged as what is known as an AMP file. The Records Management AMP is called alfresco-recordsmanagement.amp. You need a special tool to install AMP files called the Module Management Tool (MMT). The MMT is a JAR file called alfresco-mmt-3Stable.jar. To install the Records Management AMP, assuming the AMP file and the Alfresco WAR file are in the same directory, you would run:java -jar alfresco-mmt-3Stable.jar install alfresco-recordsmanagement.amp alfresco.war
The result will be a new alfresco.war and a backed up alfresco.war. Deploy the new alfresco.war to your application server to run Alfresco with the new module.I'm not sure what you mean by "Image Management". Alfresco can manage images OOTB and includes a Thumbnail Service to produce thumbnails. If you need something beyond that, take a look at the thumbnails project in the Alfresco Forge http://forge.alfresco.com/projects/thumbnails/. It also deploys as an AMP so the same instructions apply.For any sort of image manipulation your server will need to have ImageMagick installed. Instructions for installing ImageMagick vary by operating system. The ImageMagick home page is http://www.imagemagick.org.Jeff
