We want to add the "Image Upload" option to table view type multiple fields under store configuration section using system.xml. Check the below screenshot for more clarification.
Any help/suggestion will be highly appreciated. Thank you.
Try this in your System.xml file its work
<field id="logo" translate="label" type="image" sortOrder="30" showInDefault="1" showInWebsite="1" showInStore="1">
<label>Image Upload</label>
<backend_model>Magento\Config\Model\Config\Backend\Image</backend_model>
<upload_dir config="system/filesystem/media" scope_info="1">logo</upload_dir>
<base_url type="media" scope_info="1">logo</base_url>
<comment><![CDATA[Allowed file types: jpeg, gif, png.]]></comment>
</field>
Thanks
