Why do my cover images become blurry after uploading?

[MarcesMochia]

Our cover images looks fine when first uploaded, but after a couple of minutes, when visiting our site the images apear very blurry..

I’ve attached 2 images, both snipped at the same time on the same site, one images is very blurry and the other is not.. When we first uploaded the blurry image it looked fine..
