Purpose of thumb_file/photo in iPhoto?

What is the purpose of thumb_ in iPhoto?

The reason I ask is because I recently downloaded some photo and video files from an external HD  that contained my old iPhoto library .   When the photo/video files were imported to my new iMac's iPhoto, the Jpeg_plusthumb_ pictures  were both added to new iPhoto Events/Pictures.

Can I safely delete the thumb_ picture from iPhoto?

Thanks for advice.
