Check out Merge two images in php

Adapt that function to either put two images side by side (taking two parameters, each images) and also adapt it to put three images vertically (as it starts with two, you're just adding a third). This second adaptation would take three parameters of the three images to join.

Then call the functions, nesting one in the other, such as:

join3(join2($firstURL, $secondURL), 
      join2($thirdURL, $fourthURL), 
      join2($fifthURL, $sixthURL));

and you can set your URL parameters to whatever you want to dynamically call the function.
