Every time through the loop you are completely overwriting your file.

Do this instead:

elif form.has_key("filename"):
    item = form["filename"]
    if item.file:
        fp = file('1.jpg','wb')
        while 1:
            data = item.file.readline()
            if data:
                fp.write(data)
            else:
                break
        fp.close()
