[Need Help] What's that FILE OBJECT?

[daidaiworm]

I'm a green hand.
Successfully installed your function.
It's working when I input "image's path and name" in
im1 = sp.misc.imread(ImagePathName, True)

But in my project, I need read an image and manipulate it, then convert it into PIL-object.
Currently I had to write that PIL-object to hdd.

Is there any way to read that PIL-object directly.
I read the function's doc, it's working in file object. But I tried this, but failed.
fo=open('image.png','r'); im1 = sp.misc.imread(fo, True)

Please give me some guide, thanks a lot.
