Just call the GD functions as would be done in any regular PHP script.

Of course, the library must be installed on your computer. How else
could you use it?

I saw your other post, about writing text to an image. See this

Note that it's very outdated now. You should use that as an example
only as it will very likely need to be updated for version 1.3.x.
