I am using several high quality aerial photographs, and each is copyright by
someone different. How do I display different "copyright" statements only
when viewing a certain extent?
I tried the following, but it displays the copyright statement whenever the
zoom level reaches 50,000. These layers MUST be in the same group, else I
would have made separate map files. So that when the user zoms in, they get
to see more detail.
Any ideas?
My map file:
