Images not showing in WordPress Reader

Hi,
I need some help, wordpress reader has never shown a blog image with my post on the reader.

I always chose a featured image. I don’t understand what I could possibly doing wrong.

Images are also not shown to blog subscribers who receive an email and the initial paragraph when a story is released.

I have also noticed that images aren’t always picked up when the stories are posted to FB, twitter, google+ and linked through shareaholic or other third party sharers.

Please help, my stories look so boring without an image ??
