[Image-SIG] create image-instances from data strings

[Torsten Gallmeister]

Cool, that works but only for the open method. Image.save(file) and getting
values with file.getvalue() gives me the initial data of der StringIO
object.Image.save("filename") makes the correct/changed imagefile.
do you know what's  happen?

Torsten.
