Combining two images horizontally in python using OpenCV

I have four images, each slices of a larger image. If I string them together horizontally, then I get the larger image. To complete this task, I'm using python 2.7 and the OpenCV library, specifically the hconcat() function. Here is the code:

with open("tempfds.jpg", 'ab+') as f:
            f.write(cv2.hconcat(cv2.hconcat(cv2.imread("491411.jpg"),cv2.imread("491412.jpg")),cv2.hconcat(cv2.imread("491413.jpg"),cv2.imread("491414.jpg"))))

When I run it, everything works fine. But when I try to open the image itself, I get an error: Error interpreting JPEG image file (Not a JPEG file: starts with 0x86 0x7e). All the images I'm using are jpg's, so I don't understand why this error is occurring. Any insight is appreciated.

If you want to write a JPEG, you need:

cv2.imwrite('lovely.jpg', image)

where image is all your images concatenated together.
