Trying to clean up a mess and merge all catalogs to one Master Catalog

[Sheilaru]

1. Merged all catalogs to Master Catalog
2. Moved old catalogs to a separate file folder marked "Old Catalogs"
3. Ran Duplicate Finder on the Master Catalog
4. Got 11,000+ images in the Duplicate Photos Collection folder
Don't know which images I can safely delete:
This is an example of the page:


I have searched YouTube videos and cannot find the confidence to delete all the blank images.
Any guidance will fill me with delight. Thx

All the blank images are missing images. Lightroom can't locate the original image.
