I'm not sure I understand your question. I assume you are doing something along the lines of:
import base64
with open("yourfile.ext", "rb") as image_file:
encoded_string = base64.b64encode(image_file.read())
You have to open the file first of course, and read its contents - you cannot simply pass the path to the encode function.
Edit: Ok, here is an update after you have edited your original question.
First of all, remember to use raw strings (prefix the string with 'r') when using path delimiters on Windows, to prevent accidentally hitting an escape character. Second, PIL's Image.open either accepts a filename, or a file-like (that is, the object has to provide read, seek and tell methods).
That being said, you can use cStringIO to create such an object from a memory buffer:
import cStringIO
import PIL.Image
# assume data contains your decoded image
file_like = cStringIO.StringIO(data)
img = PIL.Image.open(file_like)
img.show()

Nice, but base64 is not encryption, it won't stop people from getting the data. A better use would be when sending your programs or non ascii files though a medium, which can mess up formatting or doesn't support certain data types (pastebin, minecraft's book and quill). More on reddit.com

The legacy interface does not support decoding from strings, but it does provide functions for encoding and decoding to and from file objects. It only supports the Base64 standard alphabet, and it adds newlines every 76 characters as per RFC 2045.

For the files section, this is partially irrelevant since files already contain the corresponding separators, but you can define which one to use for the "encode each line separately" and "split lines into chunks" functions. Encode each line separately: Even newline characters are converted to their Base64-encoded forms.

From the base64 package doc:
base64.encodestring:"Encode the bytes-like object s, which can contain arbitrary binary data, and return
bytescontaining the base64-encoded data, with newlines (b"\n") inserted after every 76 bytes of output, and ensuring that there is a trailing newline, as per RFC 2045 (MIME)."
You want to use
base64.b64encode:"Encode the bytes-like object s using Base64 and return the encoded
bytes."
Example:
import base64
with open("test.zip", "rb") as f:
encodedZip = base64.b64encode(f.read())
print(encodedZip.decode())
The decode() will convert the binary string to text.

Use b64encode to encode without the newlines and then decode the resulting binary string with .decode('ascii') to get a normal string.
encodedZip = base64.b64encode(zipContents).decode('ascii')
