Images shouldn't always be positive and joyful, try to grab the lead's attention by an upset photo of a celebrity.  This can go great with a money failure story.  For example, famous singer was close to bankrupt, but at the last moment he made a fortune. As a conclusion, try to use only fresh photos and relevant stories.  Do not forget to check the relevance of the image for a specific GEO.  Try different access and use you creativity.
