Images are displaying well but image size isn't optimized and images are bigger than the portlet.
Version 6.2 EE
This carousel portlet was developed by XTIVIA, the 2012 Liferay North America Partner of the Year, using Alloy UI with the goal of making it easy on a content manager or a site administrator to add carousels to a site without writing JavaScript code. The XTIVIA carousel portlet allows you (as the configurator) to configure a tag name associated with the images or web content that you want to render in the carousel; using this portlet you can have multiple carousels throughout your site.
Key Benefits:
• User configurable
• Multiple carousel portlets on a page and site
• Uses Liferay's permissioning system
• No JavaScript required
• Images or Web Content
