Hi – I have been told that I can upload my website banner images of 1920×600 px (original 1 MB size) and not to worry about it because Smush will take care of reducing the file size. But since Smush only reduces by some percentage, I am wondering if I should first use Gimp (actually I have Photoscape, does this work well?) to first reduce the file size a bit from the original, to something like 200kb. I have to crop the image first anyway, so I am already in the photo editing software. What do you recommend? Should I upload a non-reduced image of 1 MB? Or should I upload a reduced image of 200kb? What is the best way to achieve maximum image quality and fastest load time? What is the recommended max size (in kb) for a full width banner image on a page? I have these at the top of all my pages. Thank you!
