Image Size

The effect of image size

Image sizes used to be highly constrained due to the slower speed of our internet connections. Big images are slow to load. These days it is less of an issue, but you still do not want unnecessarily large images.

You webpage should load in not much more than 4 seconds, but less is better. So keep your main image to less than 300kb. Try for 100-150kb if possible.
