I really do not understand the "property" and the "setter". The "property" makes the attribute read-only, but the "setter" makes the attribute mutable. So if we want to use "property", why we need to introduce the "setter".

Where all can you "pull" (source) an image from; meaning, does it have to be a URL, or can it be a file (is that what is meant by "relative" and "absolute")? Also, how do you "format" the image/where do you put it so it can be accessed by the code and used on the webpage?
