You download the bin file from HERE and then install it. I'm not sure what other tools you are referring to. To the best of my knowledge I think image magick is included. I could be wrong though.
Thank you Mr.ESWBitto it worked for me as i expected. If you don't mind could you please tell me about alfresco auto login with Active Directory server and liferay alfresco sso integration.
Note:- Liferay 6.2 GA2 and alfresco 4.2f or latest version
