This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Liferay provides a good Content management system which caters to Images/Documents and Content.
We have a Portal running which is having loads of images/documents and web contents and Liferay has certainly done pretty well for us so far. Its easier to manage CMS through and easy to use Control Panel and the most important feature according to me is CMS caters to multi Language support. Your site can display different Content for different countries.
