Script doesn't download large images

Question

i use this script to download images from the same html page. But if images large enough, this script doesnt download properly - all images are 1,15 Kb and dont display. How can i fix it? what's wrong?

Answer 1

If you download and inspect the HTML in http://tema.ru/travel/new-york.2011.11/, you see things like

<img src="IMG_5072.jpg" alt="" width="1000" height="667" border="1" />

So this page is using relative links.

The line

parsed[2] = image["src"]

changes parsed from

['http', 'tema.ru', '/travel/new-york.2011.11/', '', '', '']

to

['http', 'tema.ru', 'IMG_5072.jpg', '', '', '']

and then forms the new url with

url = urlparse.urlunparse(parsed)

which sets url to http://tema.ru/IMG_5072.jpg which does not exist. The correct url is http://tema.ru/travel/new-york.2011.11/IMG_5072.jpg.

We can form that url with

url = urlparse.urljoin(base_url,image['src'])

so try
