What is the max size I should upload for the best quality hero image? Right now I have 3414x1695, the image looks good but the file size is 1.5 mb and when I choose cover it stretches the image a bit. I saved for web but the file size is even larger. I would like a smaller file size and I do not want the image to stretch, I would like it to fit proper. Any suggestions on this?
Also, should I upload a smaller version of the image for tablet and mobile to make sure that the image looks good on all devices?
