The particular option should be enabled to apply the featured image. See the picture below.
The featured image can be:
- Specified by adding an extended attribute in the document named ‘featured_image’ or ‘Featured Image’.
- Taken from the document’s body.
And, it can be chosen by click on the link which source to use (see picture above). There are three modes:
Extract only from the extended attribute.
separate attribute or 1st body’s image
Extract from the extended attribute. If it is not found then extract from the document’s 1st body’s image.
1st body’s image
Extract only from the document’s 1st body’s image.
The extended attribute’s value can be:
- The physical URL of the existing WordPress media picture (marked as a link or not) or inserted linked image with that URL. The plugin detects that the picture URL is the media picture and set it as a featured image. To obtain this URL, we should go to the particular image in the Media Library, click on ‘Edit’ and look at the ‘File URL’ property.
- Embedded or linked image as similar to body image. In this case, the image will be automatically uploaded and set as a featured image.
Note: The image is always placed in the media library.
