io.imsave() problems with passing arguments to plugin "freeimage"

[Sigmund]

Hallo!

As I wrote, the workaround:

by Zach worked fine for me. Now I tried the same code on a WIN 7 64 bit 
system (EPD 7.3.1) and got the following error:

Traceback (most recent call last):
  File "G:\Marwen\Summer.py", line 67, in <module>
    fi.write(summation, 
str(datensatz)+"_interval-"+str(interval_length)+"_"+str(count)+'.tif', 
fi.IO_FLAGS.TIFF_NONE)
  File 
"C:\Python27\lib\site-packages\skimage\io\_plugins\freeimage_plugin.py", 
line 538, in write
    bitmap, fi_type = _array_to_bitmap(array)
  File 
"C:\Python27\lib\site-packages\skimage\io\_plugins\freeimage_plugin.py", 
line 604, in _array_to_bitmap
    raise ValueError('Cannot write arrays of given type and shape.')
ValueError: Cannot write arrays of given type and shape.

I checked the .dtype of the array and compared them to the one on the 32bit 
and the OS X system but coutn't see any difference.

I'm reading several Images with
numpy.array(io.imread(bild, plugin="freeimage"),dtype=np.int32)
and sum then up one by one to write them out afterwards as one file.
