In the case of the infobox image specifically, the blurriness probably stems from the fact that the original image (this one) is displayed at a larger size in the infobox, thus enlarging it, which makes it show up blurry. The fix that problem, you can either upload a larger original file or shrink down the size with which the image is displayed in the infobox.
