Magento2.1 Category image upload showing preview after upload image but not working after save category.

this is magento version default bug.

To solve this issue by apply bellow patch.

Opne this url : https://github.com/magento/magento2/pull/5978/files

You have to override below core files code with file code from given URL.

vendor/magento/module-catalog/Controller/Adminhtml/Category/Image/Upload.php
vendor/magento/module-catalog/Controller/Adminhtml/Category/Save.php
vendor/magento/module-catalog/Model/Category.php
vendor/magento/module-catalog/Model/Category/Attribute/Backend/Image.php
vendor/magento/module-catalog/Model/Category/DataProvider.php

Now magento-2.1 working code for custom image attribute of category.

Answer 2

I solved this issue by setting the backend_model for my attribute in the eav_attribute table to Magento\Catalog\Model\Category\Attribute\Backend\Image

When a category is saved in Magento 2 it walks through the attributes calling the afterSave function of each attribute.

As you can see below the function Magento\Catalog\Model\Category\Attribute\Backend\Image::afterSave moves the file from the tmp folder to correct folder.

public function afterSave($object)
{
    $image = $object->getData($this->getAttribute()->getName(), null);

    if ($image !== null) {
        try {
            $this->getImageUploader()->moveFileFromTmp($image);
        } catch (\Exception $e) {
            $this->_logger->critical($e);
        }
    }
    return $this;
}

Check if you have created a preference for Magento\Catalog\Model\Category\DataProvider, and your new DataProvider has this code in it.

class DataProvider extends \Magento\Catalog\Model\Category\DataProvider {

protected function getFieldsMap()
{
    $fields = parent::getFieldsMap();
    $fields['content'][] = 'custom_attribute_name';
    return $fields;
}
