Is it safe to delete thumbnail images? Will doing so delete main images? Can't find this topic anywhere. Thank you.

Confused about thumbnail images. I have both iPhoto and Photos on my MacBook Pro with Sierra. Is it okay to delete thumbnails of the same larger photos without deleting those too? Thanks!!

Mac Pro, OS X Mavericks (10.9), about apple mail and smart groups

No. When Photos imports a photo into the library it creates a thumbnail/preview version to display in albums and other windows of the library. Deleting the thumbnail/preview also deletes the full sized original file. There's no way to separate them when deleting. Just consider them one and the same.
