We recommend that you size your images at 1500px wide - this is a suitable size for retina iPad displays and therefore will look good on other devices. Be sure to set image quality to 60% for best optimisation results.
If you are using PhotoShop you should 'Save for Web', use the JPG format and set the quality to 60%. If you require transparency you should use the PNG-24.
Some fields in Express will recommend sizes for images in that particular field, continue to optimise your quality and set the width respectively.
