I've read another thread on SO regarding image rotation here:
PIL thumbnail is rotating my image?

and I've read another thread on SO about EXIF preservation here:
Preserve exif data of image with PIL when resize(create thumbnail)

Unfortunately, after implementing the suggestions above, it seems that I can only have either:
1) a saved rotated image without EXIF data
or
2) a non-rotated image with EXIF data
but it seems that I can't have both.

I'm hoping I can get some help to fix what I thought was a real simple problem, but has been turning into a scream-fest against my computer for the past few hours.

Here's the relevant parts of my code:

from PIL import Image, ExifTags

import piexif

currImage = Image.open(inFileName)

exif_dict = piexif.load(currImage.info["exif"])



for orientation in ExifTags.TAGS.keys():

    if ExifTags.TAGS[orientation]=='Orientation':

        break

exif=dict(currImage._getexif().items())



if exif[orientation] == 3:

    currImage=currImage.rotate(180, expand=True)

elif exif[orientation] == 6:

    currImage=currImage.rotate(270, expand=True)

elif exif[orientation] == 8:

    currImage=currImage.rotate(90, expand=True)



currWidth, currHeight = currImage.size



# Here is where I can only do one or the other.  Don't know enough about how to get both

exif_bytes = piexif.dump(exif_dict)

#exif_bytes = piexif.dump(exif)



maxImageDimension = [1280, 640, 360, 160]

for imgDim in maxImageDimension:

    thumbRatio = imgDim / max(currWidth, currHeight)

    # note that because Python's round function is mathematically incorrect, I have to do the following workaround

    newWidth = int(Decimal(str(thumbRatio * currWidth)).quantize(Decimal('0.'), rounding=ROUND_UP))

    newHeight = int(Decimal(str(thumbRatio * currHeight)).quantize(Decimal('0.'), rounding=ROUND_UP))

    # copy currImage object

    newImage = currImage

    # note that I have to do resize method because thumbnail method has same rounding problem

    newImage = newImage.resize((newWidth, newHeight))

    # save the thumbnail

    if imgDim == 1280:

        outFileName = destinationDir + '\' + file[:len(file)-4] + '.jpg'

    else:

        outFileName = destinationDir + '\' + file[:len(file)-4] + '-' + str(newWidth) + 'x' + str(newHeight) + '.jpg'

    print('Writing: ' + outFileName)



    # Here is where I have to choose between exif or exif_bytes when saving but I can only get one or the other desired result

    newImage.save(outFileName, exif=exif_bytes)  



print('n')



currImage.close()

newImage.close()

Thanks in advance.
