1. Show case pdf in grid view for ARTICLES page using download manager plugin as in chennaiscoop.in/epaper [customized for better display and blocked update to avoid overwritecodes]
2. Use foo gallery pluginworks fine in Gallery page for photo gallery - http://gpage.in/crescentdays/photo-gallery/ but is not working at the above mentioned url
3. Using Gallery Plugin to display videos in Grid view works fine at http://sennighttimes.in/churchadmin/videos/ but not working at the above mentioned url
