Because the imageData holds the data for the pixels being displayed (even
if they are all transparent/no color), so it cannot be empty unless the
image has zero width and/or zero size. If the image object has a size, it
has pixels, therefore it has imageData (even all zeros) for each pixel.

However, if you create a new image and look at the text property of the
image, you will see that it's empty until you paint something in the image.
