The image that should erase everything that was in the image of a human being or an animal, it must obliterate her face only, and enough blur her face for the rest of her body, while the images of trees, stones, mountains, sun, moon, and stars, and so on, this is not okay, and should not be smudge. the image of an eye only or face only: this is not the thing, because it is not in, that's part of it, not image

Narrated 'A’ishah: I stuffed for the Prophet (Peace and blessings be
upon him) a pillow decorated with pictures (of animals) which looked
like a Namruqah (i.e. a small cushion). He came and stood among the
people with excitement apparent on his face. I said, "O Allah's
Apostle! What is wrong?" He said, "What is this pillow?" I said, "I
have prepared this pillow for you, so that you may recline on it." He
said, "Don't you know that angels do not enter a house wherein there
are pictures; and whoever makes a picture will be punished on the Day
of Resurrection and will be asked to give life to (what he has
created)?" [Bukhari 4:47]
