Hello,
First of all, thank you for your purchase.
1. Please check this video for details on how to remove duplicate featured images from posts: https://www.youtube.com/watch?v=Ese19rPj0eQ
2. The ‘Page Screenshot Width’ ‘Page Screenshot Height’ settings refer to the size of the screenshot which the plugin is able to do of the scraped pages. You can add a screenshot of the scraped page to the content, if you add in the ‘Generated Post Content’ settings field, from rule settings (for each rule separately), the following shortcode: %%item_show_screenshot%%
3. To skip posts without featured images, please go to the plugin’s ‘Main Settings’ menu -> check the ‘Skip Posts That Do Not Have Images’ checkbox -> save settings.
I hope this info helps.
