I have a plugin, Image-Headlines (v2.7), and I want to write code in my page so it checks to see if the function exists. However, I can't figure out how to determine what the function name is that I need to check to know if the plugin has been activated.
Does anybody know how, in general, I can determine function name that a plugin uses to show that it has been activated? Or specifically, what the function name is that exists when the Image Headlines plugin is active?
