The regex matches only the names of the images. Try matching their 
entire URLs.

For each URL, download the image and save it into the folder. You can
make a path for each image by joining (That's a hint! Look in os.path)
the path of the folder with the name of the image.

Don't use a 'bare' except. It swallows EVERY exception. Catch only what
you're willing to handle, and let the other exceptions just show
themselves.
