I've got a dilemma with the images on my website that are linked from image hosting sites. They all need to be displayed at 100% width, but some of them have huge pixel dimensions which cause slow loading times. Is there a way to resize the images without losing the 100% width requirement in order to speed up the loading process? For instance, can I set the horizontal pixel limit to 1440px and adjust the vertical pixel accordingly while maintaining the 100% width?
