Yes you have to filter your queryset. You are currently updating all objects.

image_new = UserWithImage.objects.filter(user=request.user).update(image=image_fs)

or if you do not want to update the user which does the request you call it like

user = User.objects.get(id=1)
image_new = UserWithImage.objects.filter(user=user).update(image=image_fs)

You first need to select the user and then update the image. But after this, remember to remove the old image, it would still be stored in your media folder, even if it was replaced.

Here is how i would do it

if 'imagechange' in request.POST and request.FILES['image']:
    image = request.FILES['image']
    fs = FileSystemStorage()
    image_fs = fs.save(image.name, image)
    user_with_image = UserWithImage.objects.get(user=request.user)
    # get the old image path
    old_image_path = user_with_image.image.path
    #replace the image and save
    user_with_image.image = image_fs
    user_with_image.save()

    # delete the old image
    if os.path.exists(old_image_path):
        os.remove(old_image_path)
