title: decrease string in python doesn't works
body: <p>I have a problem to cut the url that i get as result from Beautifulsoup, i've used this code to retrieve the url.</p>
  
  <pre><code>import urllib2
  from bs4 import BeautifulSoup
  
  url = 'http://192.168.0.184:88/cgi-bin/CGIProxy.fcgi? cmd=snapPicture&amp;usr=USER&amp;pwd=PASS'
  html = urllib2.urlopen(url)
  soup = BeautifulSoup(html, "html5lib")
  imgs = soup.findAll("img")
  print imgs
  print imgs[1:]
  </code></pre>
  
  <p>As result from print imgs i get <code>[&lt;img src="../snapPic/Snap_20160401-110642.jpg"/&gt;]</code>
  I want to cut the unwanted characters from this string so i try to use for eg. print imgs[1:] but as result i get []</p>
  
  <p>Any tips or solutions?
  I want to rebuild the imgs string to the correct image url
  <code>imgs string = &lt;img src="../snapPic/Snap_20160401-110642.jpg"/&gt;</code>
  wanted result = <code>http://192.168.0.184:88/snapPic/Snap_20160401-110642.jpg</code></p>
