如何为特定帖子类型添加多个图片上传metabox（） _WordPress主题

我正在创建一个主题, 在其中创建了一些自定义帖子类型的产品和一些自定义元框, 以提交其各自的自定义信息, 例如其费用和有效期。
通过执行一些搜索add_theme_support(‘ post-thumbnails’ ); , 我能够添加一个特色图片列来上传与特定帖子相关的特色图片。但是它只允许我添加单个图像, 并且我想上传与一个特定的自定义帖子相关的多个图像。例如单个产品的不同图像。
为此, 我在互联网上找到了不同的解决方案, 其中一个最适合我的问题的解决方案是这个, 但同样, 它仅允许我上传一张图片, 但与特色图片不同。
WordPress是否有任何功能可以上传多个图像, 例如功能性图像上传(特别是针对单个帖子), 还是该任务有任何插件？

#2【如何为特定帖子类型添加多个图片上传metabox（）】噢, 谢谢你告诉我布拉索菲洛。正确的答案是, 可以通过帖子标题下方的媒体上传按钮上传多个图像, 并可以通过使用画廊短代码(例如)在前端的画廊中显示这些图像：-
