Fail to install haul? It is probably caused by lxml.

Usage

import haul

url = 'http://gibuloto.tumblr.com/post/62525699435/fuck-yeah'
result = haul.find_images(url)

print(result.image_urls)
"""
output:
[
    'http://25.media.tumblr.com/3f5f10d7216f1dd5eacb5eb3e302286a/tumblr_mtpcwdzKBT1qh9n5lo1_500.png',

Advanced Usage

Custom finder / extender pipeline:

from haul import Haul
from haul.compat import str


def img_data_src_finder(pipeline_index,
                        soup,
                        finder_image_urls=[],
                        *args, **kwargs):
    """
    Find image URL in <img>'s data-src attribute
    """

    now_finder_image_urls = []

    for img in soup.find_all('img'):
        src = img.get('data-src', None)
        if src:
            src = str(src)
            now_finder_image_urls.append(src)

    output = {}
    output['finder_image_urls'] = finder_image_urls + now_finder_image_urls

    return output

MY_FINDER_PIPELINE = (
    'haul.finders.pipeline.html.img_src_finder',
    'haul.finders.pipeline.css.background_image_finder',
    img_data_src_finder,
)

GOOGLE_SITES_EXTENDER_PIEPLINE = (
    'haul.extenders.pipeline.google.blogspot_s1600_extender',
    'haul.extenders.pipeline.google.ggpht_s1600_extender',
    'haul.extenders.pipeline.google.googleusercontent_s1600_extender',
)

url = 'http://fashion-fever.nl/dressing-up/'
h = Haul(parser='lxml',
         finder_pipeline=MY_FINDER_PIPELINE,
         extender_pipeline=GOOGLE_SITES_EXTENDER_PIEPLINE)
result = h.find_images(url, extend=True)
