Replacing
>>> self.imagefiles = glob.glob(dirName + "/*.gif")
>>> self.imagefiles = cycle(self.imagefiles)
with
self.imagefiles = image_cycler(os.path.join(dirname, "*.gif"))
where image_cycler() looks as follows
def image_cycler(pattern):
while True:
for fn in glob.glob(pattern):
yield fn
would be the simplest way.
