Oh, yeah, that's right. I just didn't notice it... Thanks for
correcting me! Actually it wouldn't have mattered (I think) because
the list contains x.jpg and x_thumb.jpg which have been collected by
os.listdir(). At least I suppose that it would be like [x.jpg,
x_thumb.jpg, y.jpg, y_thumb.jpg] or am I completely wrong? But thanks
for good suggestions, I replaced my code with the list comprehension
method and it works now. Thanks!

Yours,
