I'm trying to scrape the images (or the images link) of this forum (<http://www.xossip.com/showthread.php?t=1384077>) . I've tried beautiful soup 4 and here is the code I tried:

```
import requests
from bs4 import BeautifulSoup

def spider(max_pages):
    page = 1
    while page <= max_pages:
        url = 'http://www.xossip.com/showthread.php?t=1384077&page=' + str(page)
        sourcecode= requests.get(url)
        plaintext = sourcecode.text
        soup = BeautifulSoup(plaintext)
        for link in soup.findAll('a',{'class': 'alt1'}):
            src = link.get('src')
            print(src)

        page += 1
spider(1)

```

How should I correct it so that I get links of images like `pzy.be/example` ?
