I'm not sure if I get the difference between the spatial domain and the frequency domain in regards to the images itself - does the spacial domain refer to the image itself, while the frequency domain refers to the sharpness of edges/colors or something like that?

The "domain" refers to the basis in which an image (a signal) is represented. Just like the same point can take on different coordinates depending on which coordinate system it is represented in, an image can take on different representations depending on whether it is represented by the magnitudes of its pixels, or as a combination of sin waves.
