I am adding photos in Sigil for an epub I am creating. I have noticed that if I add 2 images - one that is 150 px wide and another one at 600 px wide using the same class for width they show on the screen the same size with one blurry and one crisp (obviously enlarging my smaller pic to meet their default size). I want the one that is 150 px to show up small. I want to be able to have the image come in at 100% not always have to create a class to resize them down from Sigils default. Why doesn't sigil bring them in at the size they are? Am I missing something here?
