    Thanks for looking at my code. I'm glad to know I hadn't overlooked something silly.

    As it is, I am trying to make an extension to re-display or mobilize certain kinds of websites. Imagine if I went to a website full of thumbnails, and the script grabbed all of the linked full-size images. There's other websites and whatnot, but I was mostly playing around with extensions for now.

    Thanks again for the help.

    The HTML I'm using works everywhere, but not loaded through in an extension. That's my whole goal, I am trying to replace webbrowser.open("local file") for use in an extension. I haven't tried to load a local image using my HTML doc, I'll try that out.
    Here is an example of my HTML when I point it at "http://xkcd.com"

    <body bgcolor="#000000">
    <img src="http://imgs.xkcd.com/static/terrible_small_logo.png" alt="http://imgs.xkcd.com/static/terrible_small_logo.png" ><br><br>
    <img src="http://imgs.xkcd.com/comics/tire_swing.png" alt="http://imgs.xkcd.com/comics/tire_swing.png" ><br><br>
    <img src="http://imgs.xkcd.com/store/te-pages-sb.png" alt="http://imgs.xkcd.com/store/te-pages-sb.png" ><br><br>
    <img src="http://imgs.xkcd.com/s/a899e84.jpg" alt="http://imgs.xkcd.com/s/a899e84.jpg" >

    Here is my full code (cleaned and formatted, but just as dysfunctional when used as an extension):

    # coding: utf-8
    import appex
    from urllib2 import urlopen
    import os, console, requests, urlparse
    def write_text(name, text, writ='w'):
      with open(name, writ) as o:
    def img_page(file_list, link_list=None):
      if link_list is None: link_list = file_list
      links = zip(file_list, link_list)
      x = '<br><br>\n'.join(['<img src="{0}" alt="{1}" >'.format(a,b) for a,b in links])
      y = """
    <body bgcolor="#000000">
      return y
    def view_doc(text):
      import ui
      w = ui.WebView()
      w.scales_page_to_fit = False
    def open_file(file_path):
      import ui
      file_path = os.path.abspath(file_path)
      file_path = urlparse.urljoin('file://', os.path.abspath(file_path))
      #v = ui.View()
      #file_path = 'http://xkcd.com'
      wv = ui.WebView()
      #v.frame = (0,0,320,568)
      #wv.frame = (0,0,320,568)
    def view_temp_index(file_url_list):
      temp_fn = '__temp.html'
      write_text(temp_fn, img_page(file_url_list))
    def get_Pic_Links_Content(content,url=None):
      from bs4 import BeautifulSoup as bs
      if url is None:
        url = '' # 'http://'
      s = bs(content)
      p = s.findAll('img')
      pics = []
      for x in p:
        y = urlparse.urljoin(url, x['src'])
        if y not in pics:
      return pics
    def get_Pic_Links(url):
      r = requests.get(url)
      #print 'viewing pics from url:', r.url
      return get_Pic_Links_Content(r.content, url)
    def pick(url):
      choice = console.alert('View:','Pick where to view source:','Make File','View Directly','Console')
      pics = get_Pic_Links(url)
      if choice == 1:
      elif choice == 2:
        print '\n'.join(pics)
    def main():
      if not appex.is_running_extension():
        print '\nRunning using test data...'
        url = 'http://xkcd.com'
        url = appex.get_url()
      if url:
        print 'No input URL found.'
    if __name__ == '__main__':

    Correct me if I'm wrong, but does the memory limit while running Python as an appex extension prevent us from loading things with WebView.load_url or WebView.load_html ?

    I've managed to get a local html file to load, but it will not populate its img tags, images will not load and leave the default blank bar/box ( "<img src="http://url.jpg"> ). The same html file will load perfectly using ui.webview or webbrowser NOT running from an extension (the html doc will work anywhere and everywhere else).

    import ui
    def view(text):
      v = ui.View()
      wv = ui.WebView()
      v.frame = (0,0,320,568)
      wv.frame = (0,0,320,568)

    There's a cleaned up example of the function called to run my html doc as a string, though I've also tried running as a local file.
