If you want a quick fix, just write the output file after processing
each file, and set the variable that stores the image to null.  This
should automatically happen if you reuse the same variables to store
the image.  I am curious to see how you coded this so the memory grows
with each additional image.

If it is a one time job, you should run the script from the command
line (no time limit, or memory limit).  This is not a realistic task
for a web request, if you want to implement background processing then
a scheduler/queue is the way to go.
