Not working at all

Hi,

Remember that an image attached to the post means that the image was uploaded from that post edit screen. If your images were uploaded from another post or the media library, WordPress does not attach the image to your post in the database.

That means that when you click the Add Media button, then click to Media Library tab, and select “Uploaded to this post” in the dropdown, you must see at least one image. If you see the “No items found.” message, that means that your images were not uploaded within that post. And therefore, the plugin can’t use any image to set as feature image.

If you can see images when selecting “Uploaded to this post” but the plugin is not using it for feature image. You need to try for theme/plugins conflicting. Try using a WordPress default theme (i.e. Twenty Fifteen) and disabling all other plugins.

I have tested just a few seconds ago the plugin with WordPress 4.1 default installation and it’s working fine.

Thanks for your all kind information and explanation but unfortunately I can not see any image when I click the Add Media button>Media Library tab, and then “Uploaded to this post” in the dropdown. Its means that my images were not uploaded within that post.
Never mind I am going to do manually.:)

Thanks again for your kind reply.
