It doesn't work with RSS Pages for WordPress v3

I downloaded the plug-in and I tried to install but it does not work with RSS Pages for WordPress v3+ plug in at all.
In RSS and RSS2 it shows only the image file name, and in Atom no image. The plug in installation instruction did not explain clearly how to and where to place to microcode in order to configure the plug in. The author has to create a YouTube video in order explain how to install the plug-in successfully.
