If you have a bitmap image, like png, jpg, gif, bmp (oh dear..), you could add the following lines in front of your call to c.save():

from reportlab.lib.units import inch, cm  # 72 dpi -> inch = 72 
c.drawImage('my.png',2.5*cm, 5*cm, 4*inch, 3*inch) # parameters: filename, spacing from left and bottom, with width and height

Reportlab doesn't seem to handle vector images well, even with PIL installed, it will result in an IOError: cannot identify image file if you use it on the image exported as pdf. However, you could e.g. use ghostscript to merge pdfs, regardless of their content. But then you won't have the typical reportlab styling.
