Compress your custom media into a zip file without a password, and then add the compressed file to your project. You can also export custom media in your project. Note that when you increase or decrease the media reference, you also need to update the custom media in your project to ensure that the page media is displayed correctly.

将您自定义媒体压缩为无密码的zip文件，让后将该压缩文件添加到项目中。您也可以将项目中的自定义媒体导出。请注意，在增加或减少媒体引用后，也要同时更新项目中的自定义媒体，保证网页媒体显示正常。
