Thanks, Niphlod - that looks like it should solve the issue. Just have a
follow-up question - what's the best way to pass the location of the file
to the 'open()' function? I've tried a few things, including the following:
image_filename_as_list = current_image.image.split('.')
cur_image_location = path_join(request.folder, 'uploads',
'temp_user_images',
'.'.join(image_filename_as_list[:2]), image_filename_as_list[2
][:2], current_image.image)
print "cur_image_location:",cur_image_location
stream = open(cur_image_location, 'rb')
The print statement seems to show the correct file location. However, the
open() command causes an exception, and the exception shows a different
file path from what was output by the print statement; specifically, the
'temp_user_images' portion is modified to just 'images'. Any
recommendations? Thank you.
