Hello, my friend,
Can you provide us with some more info about your issue? Are you testing the plugin as it is explained in its description in the wordpress.org plugin page?
Also could you send us the results of the Pring debug and Print diagnostics buttons in the plugin settings page?
Lastly, if it is possible for you to share you website url with us, we could take a look at your images directly and debug any issues.
Cheers,
Takis
