Magento 2 How to display placeholder image to image preview backend UI component form

In my custom module i have custom UI component form and i add file upload filed to this form.

Form is working fine while Add or Edit, when upload file image preview is display,but i want to display default image preview once file is not uploaded and display a placeholder image to image preview section.

Below is image upload code.

<field name="image">

        <argument name="data" xsi:type="array">

            <item name="config" xsi:type="array">

                <item name="dataType" xsi:type="string">string</item>

                <item name="source" xsi:type="string">image</item>

                <item name="label" xsi:type="string" translate="true">Image</item>

                <item name="visible" xsi:type="boolean">true</item>

                <item name="formElement" xsi:type="string">fileUploader</item>

                <item name="placeholderType" xsi:type="document">document</item>

                <item name="elementTmpl" xsi:type="string">ui/form/element/uploader/uploader</item>

                <item name="previewTmpl" xsi:type="string">Namespace_Modulename/image-preview</item>

                <item name="validation" xsi:type="array">

                    <item name="required-entry" xsi:type="boolean">true</item>

                </item>

                <item name="uploaderConfig" xsi:type="array">

                    <item name="url" xsi:type="url" path="managelabels/productlabel/upload"/>

                </item>

            </item>

        </argument>

    </field>

After search a lot and found something to display placeholder image this link. in this documentation they use placeholderType argument to Defines the preview type.

But i have no idea to how to implement this argument to my custom form.

Any help would be appreciated! Thanks.
