This is more pythonic (also more efficient):
filenames = [f for f in filenames if f.endswith(".png")]
Your method with the loop won't work in general. Do it like this.

ah! google is my friend.
for f in filenames:
if not f.endswith('.png')
filenames.remove(f)
Along with lots of warnings to copy from one list to another rather
than delete on an iterating list. But really how much harm could it
do? lol... I think.

I find myself often iterating a list looking to remove the
undesireable elements. I want to do this:
for f in filenames:
if not f.endswith('.png')
f.delete()
But I find myself having to do this:
for i in range(len(filenames))::
if not filenames[i].endswith(".png"):
