Hi am,
You could use something like StringIO which holds data and exposes a
read method so it acts like a file.
Here's an example which creates a new album, adds an image, then
deletes the album. The test image's data is in a string buffer instead
of a file.
import StringIO
import atom
import gdata
import gdata.service
# Create the test image
data = StringIO.StringIO('\xff\xd8\xff\xe0\x00\x10JFIF

Is this what you meant by using something other than a file?
Happy coding,
