[Plugin: WP Responsive Data Image] Great plugin but not working

Hi Sir,

I’ve been looking for a plugin like this and I was very excited to find this one. I followed every bit of instruction but I don’t seem to get this work. The image is not displaying at all, not sure where I went wrong. I’m wondering if this plugin works on wordpress version 3.1.2. Please give me some advice. Thank you

Sameer
