If you are having trouble uploading images that are larger than 2560px in height or in width this is the appropriate solution. Try not to install an external function to manipulate WordPress for simple overrides such as this.

Add the following code to functions.php

add_filter( 'big_image_size_threshold', '__return_false' );

Then re-adjust the WordPress Media Settings

Through the WordPress dashboard increase the settings for the maximum size of images to be uploaded.

1. From the dashboard go to Settings > Media
2. Over here increase the “Large size” settings to a maximum size, for example 9999px of Max Width and Max Height.
3. Save changes
