So, we want it on, to make sure that the Width is linked to the Height, so that when we resize the image, the original proportion of width to height is preserved and the image doesn't look squeezed or stretched. If I click it, this is what it looks like when it's off. First, make sure that this Link icon is on. So, there's just a couple of things to check here.

Before we resize this image, let's check how big it is to start with.
