Hello,
Please be sure to use the latest plugin version: v 5.3.3.1
Also, if you are using this version, images are probably duplicated because they are found multiple times in posts, or the posts were created multiple times (deleted and recreated).
To add attachments to generated posts (and to be able to process the images with plugins), please go to the plugin’s ‘Main Settings’ and uncheck the ‘Do Not Attach Copied Images From Content To Posts’ checkbox -> save settings.
Also, if you wish to use the images from their original location, you can uncheck the ‘Copy Images From Content Locally’ checkbox, from the plugin’s ‘Main Settings’ menu.
Regards,
Szabi – CodeRevolution.
