Try to convert your destination image with  Image.mode("RGBA").
I had similar problems. The solution was to create an alpha channel
and merge the images using  Image.composite. This was my code:
        # Original image is "im"
        # Remove transparency
        white = Image.new("RGB",im.size,(255,255,255)) # Create new 
white image
        r,g,b,a = im.split()
        im = Image.composite(im,white,a) # Create a composite

This is for removing transparency (make transparent areas white), but 
probably you
can create an alpha channel for the new image being paster and make a
