Uploaded Images are not showing in realted posts or pages after migration

I have installed this plugin ( Version 1.0 ) in local machine. It is working fine no doubt. But whenever I move my project to live server or another local machine including this plugin, the images are not showing in the related post or page. I had to upload new images for server or machine.I have moved my project in right process. I have checked the previous uploaded images are in media section. But i don’t understand why such problem is occurring.I have tried several time but same problem occurred every time. Can you please help me? Thanks in advance.
