Well, it's not *necessarily* a bad idea to make individual resources
for each of those segments. It can often make sense to make a resource
which only manages children.
However, if you do want to handle all of those parameters at once,
then override locateChild on your "images" resource. It will be passed
a context (probably soon to become a request) and segments. The
segments will be a tuple like ("600x800", "watermark", "file_a.png").
Then locateChild should "return imageResource, ()", where () means
"there should be no further processing of segments".
