Hello!
If you upload the image via the plugin’s “Select image” buttons or set one as a featured image, then TSF can obtain that data from the stored image’s metadata. If the image is obtained from the content automatically or via manual URL input, then it won’t obtain that information (the extra URL parsing and database lookups are slow and not worth it).
There are several filters (depending on where the image URL is obtained from), but I recommend keeping it simple.
For reference, the filters are the_seo_framework_generated_image_details
and the_seo_framework_custom_image_details
.
