这可以使用block filters.

首先，您需要过滤图像块的块属性，以便能够保存新项目：

const { addFilter } = wp.hooks;
function filterAttributes( settings, name ) {

    if ( \'core/image\' === name && settings.attributes ) {

        settings.attributes.description = {
            type: \'string\',
            default: \'\'
        };

        settings.attributes.nopin = {
            type: \'boolean\',
            default: false
        };
     }
    return settings;
 }

addFilter( \'blocks.registerBlockType\', \'wpse\', filterAttributes );

接下来，您需要过滤图像块的InspectorControl以添加新控件：

const { addFilter } = wp.hooks;
const { createHigherOrderComponent } = wp.compose;
const withInspectorControls = createHigherOrderComponent( ( BlockEdit ) => {

    return ( props ) => {
        return (
            <>
                { ( \'core/image\' !== props.name ) &&
                    <InspectorControls>
                        // YOUR CUSTOM CONTROLS GO HERE
                    </InspectorControls>
                }
                <BlockEdit { ...props } /> // THIS IS ALL OF THE OTHER CONTROLS AND CAN GO ABOVE YOUR STUFF AS WELL
            </>
        );
    };
}, \'withInspectorControl\' );

addFilter( \'editor.BlockEdit\', \'wpse\', withInspectorControls );

您需要管理自定义控件部分，因为我不知道那里的详细信息。

希望这有帮助！
