上传图片的时候，有时候会遇到这样的问题：

The server cannot process the image. This can happen if the server is busy or does not have enough resources to complete the task. Uploading a smaller image may help. Suggested maximum size is 2560 pixels.

可以试试下面的插件，这个插件只有一行代码。

Disable "BIG Image" Threshold

插件代码：

add_filter( ‘big_image_size_threshold’, ‘__return_false’ );
