You can check the size of your photo by opening the folder containing your picture, and then right-clicking on it. Select 'Properties' - the size of your picture will be shown.
Remember 1MB = 1000KB. To make large pictures suitable for uploading you will need to resize or compress them. You can compress them with your usual Photo Editing software.
