Slider images fuzzy after an update

My slider has been working fine for 2 years and I recently updated one of my photos on the page, didn’t even do anything to the slider itself and all the sudden the slider shows fuzzy images. I tried to recreate another slider, same thing. However when I go to internet explore it shows completely fine, sharp images. But Chrome and mobile all display fuzzy images. WHY?? I don’t what else I can do here. Thanks for the help.
