The images are high quality. I mean, look at the first five posts and their respective thumbnail on the front page of the blog.
But when those same images appear on the slider, they get blurred out. I don’t know what’s going on. The images are high-res so this should not be happening. I resized them to 800×484 to fit the slider. In the past it worked fine but I have re-installed wordpress and now it doesn’t seem to work.
