|
This example would be called from a page with a tag like: <img
|
|
src="button.php?text=text">. The above button.php script
|
|
then takes this "text" string and overlays it on top of a
|
|
base image which in this case is "images/button1.png"
|
|
and outputs the resulting image. This is a very convenient way to
|
|
avoid having to draw new button images every time you want to
|
|
change the text of a button. With this method they are
|
|
dynamically generated.
