[Multiplatform] Thumbnails of all (gif, jpeg, and png) images in a directory

Thanks Dorrin for your Thumbnailer!
I hope you don't mind, but I did some minor fixes and made your script more portable. Now, you can use it on Windows too.
By the way, as I revealed there is no dependency of "from mod_python import apache", so I removed it.



import os

import re

from PIL import Image



header = '''



Directory Listing

'''

images_per_row = 5

max_width,max_height = 150,150



path = os.path.dirname(__file__)

  

def thumbnail(filename):

  thumbsdir = os.path.join(path, ".thumbnails")

  thumbfile = os.path.join(thumbsdir, filename)

  if os.path.exists(thumbfile):

    return



  if not os.path.exists(thumbsdir):

    os.mkdir(thumbsdir);

    

  filepath = os.path.join(path, filename)

  image = Image.open(filepath)

  image.thumbnail((max_width, max_height), Image.ANTIALIAS)

  image.save(thumbfile)



def index(req):

  return_value = header



  dir_list = os.listdir(path)

  image_list = []



  search = re.compile("(.*\.[Jj][Pp][Ee]?[Gg]$)|(.*\.[Pp][Nn][Gg]$)|(.*\.[Gg][Ii][Ff]$)")



  image_count = 0

  for file in dir_list:

    if search.match(file):

      image_count += 1

      image_list.append(file)



  if image_count > 0:

    image_list.sort()

    num_rows = image_count / images_per_row



    image_num = 0

    return_value += '\n'


    for image in image_list:

      thumbnail(image)

      image_num += 1

      return_value += '\n'


      else:

        return_value += '\n'


  return_value += "
'



      if image_num % images_per_row:

        return_value += '

"

  return return_value

Here is small test script.
It generates thumbnails with Dorrin's script, then grabs HTML output and writes it to index.html file, so you get nice index page.



import thumbnail

import os



html = thumbnail.index(0)



htmlfile = os.path.join(os.getcwd(), "index.html")

f = open(htmlfile, "w")

f.write(html);

f.close()
