Help! My jpeg banner for website is blurry no matter what I do

Based on your comment, your ratio is way off. You can take a 200 x 100 image and put it into a 100 x 50 slot because the ratio is still the same so it will look good. But taking a 2213 x 519 (4.26 ratio) and stretching it to 920 x 174 (5.29 ratio) clearly is going to make the image blurry.
