A Class is a template for an object, you create it once and any changes
affect every object.

An object is an instance of a class, it contains data, properties etc.
Changing that just changes the object and it is common to change the
information in an object.

Karl I think you are trying to change the image object in an object. The
syntax for that depends upon what you are trying to do but /myobject/myimage
might be the url to your image.
