Downloaded HD images have turned to blurry in my gallery.

[Android Central Question]

The images i have downloaded from google images in hd, I've had these images for a year in my Samsung S7 gallery. They were clear the other day and now all of them are blurry/pixelated. Why has my collection of downloaded HD images turned blurry?
