Thanks a lot! This is what I ended up with. (I would like to get rar archive support, but browsing the web it looks like rar support isn't in any python library (yet)) :-( Anyway, I was able to use the below code unchanged to create thumbnails in nautilus based on the first .jpg file in a .zip archive.
Is there any rar support module in python? Thanks again. #!/usr/bin/python import zipfile import sys import gnomevfs import Image import StringIO inURL=gnomevfs.get_local_path_from_uri(sys.argv[1]) outURL=sys.argv[2] zip=zipfile.ZipFile(inURL,mode="r") jpeglist=[x for x in zip.namelist() if '.jp' in x] try: picture=zip.read(jpeglist[0]) except IndexError: print 'No jpeg found' zip.close() #close the file, since we no longer have need of it image = Image.open(StringIO.StringIO(picture)) # create image object from file-like object image.thumbnail((128,128),Image.ANTIALIAS) #create the thumbnail image.save (outURL, "PNG") #output the file in the proper format -- http://mail.python.org/mailman/listinfo/python-list
