<page layout="1column" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
<body>

    <referenceContainer name="content">
        <referenceBlock name="product.info.addtocart">
            <action method="setTemplate">
                <argument name="template" xsi:type="string">namespace_Customtab::product/view/gallery.phtml</argument>
            </action>
        </referenceBlock>

Use this:

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>        
        <referenceBlock name="product.info.media.image">
            <action method="setTemplate">
                <argument name="template" xsi:type="string">Namespace_Customtab::product/view/gallery.phtml</argument>
            </action>
        </referenceBlock>
    </body>
</page>
