Image Focal Point
Sometimes when you add an image to your site it may crop a part of the image that you don't want it to - adjusting the Image Focal Point will solve this issue!
Adjusting the Focal Point
Whenever you add an image you will see a window pop up similar to the one below. You will notice the grey circle on the images (highlighted in a red square). If you click and drag this circle to the part of the image you want it to focus on, Squarespace will optimise the image to keep this point centred when scaling for different screen sizes and devices.
