grab the big-ones (img)

hi,
little prob to fetch the real pictures from the feeds
to fetch the thumbnails is not the goal i think.
can i fetch the big ones?

here are the links from inside html:

the thumbnail
Code:
http://www.ngz-online.de/polopoly_fs/1.1255103.1305792647!/httpImage/1593972352.jpg_gen/derivatives/rpo54_195/1593972352.jpg
the real (big) pic
Code:
http://www.ngz-online.de/polopoly_fs/1.1255103.1305792647!/httpImage/1593972352.jpg_gen/derivatives/rpoPanorama_786/1593972352.jpg

o.k. that is tooooo difficult for me at beginner.
i want to read books to learn it.

is this the right way to make it absolut:

soup = BeautifulSoup()
tag1 = Tag(soup, "mytag")
tag2 = Tag(soup, "myOtherTag")

I just meant add the http://servername part to the links.

img['src'] = 'http://servername-whatever/' + img['src'].replace('xx', 'yy')

ah o.k. ,

i understand now!

but it show's like that the target picture is in a script-container also.

i believe , this is much more difficult.

i let it be and make a bit more simpler stuff.

thank you for assistance.

greetings
