Here is a fun one:
du -ha | grep -i "\.png"

What this does is generate a listing of the sizes of *all* the files and
then filters out those which have .png in it's name.  (The `i' is for case
insensitivity)

An advantage of this from using the `find...` syntax is that it doesn't
give an argument overflow when your looking at large numbers of files, and
the time is relatively the same since querying a file / directory for the
file handles and querying with a request for size is relatively the same
amount of cost.
