How can I delete auto backup photos from my gallery without deleting other images

[AC Question]

Hi

Saw some unwanted pictures in my auto backup file and I wanted to delete them,so I tried google photos,moved the photos to the bin and permanently remove them from the bin,then I searched through gallery and I cant delete the images,I found a way that you clear data and cache and it will delete them,but it also deletes other pictures
Is there any other way to delete auto backup pictures without affecting others
