Posted 2021-05-04

/**
 * 
 * This removes the ability to add the FULL image size into a post, it does not alter or delete the image
 * Add whataever extra image sizes to the insert dropdown in WordPress you create via add_image_size
 * 
 *  For now we have to do it this way to make the labels translatable, see trac ref below.
 *
 *  If your theme has $content_width GLOBAL make sure and remove it
