php - How can I add custom image sizes to wordpress but have them in the admin? -


i know how use add_image_size in php register new size can used in templates. makes images in size, when they're uploaded.

the sizes added don't show in admin, though.

so 2 questions...

  • how can image sizes make show in 'upload image' thing when bloggers make new post?

  • is there way list in admin bloggers can add new ones without having change php code?

or doing wrong, not putting add_image_size call in right place/file? sizes supposed show in upload menu section?

wordpress doesn't show custom image size options in media lightbox, can add them using attachment_fields_to_edit filter. below add options custom image sizes have defined.

add_filter('attachment_fields_to_edit', 'my_attachment_fields_to_edit_filter', 100, 2);  function my_attachment_fields_to_edit_filter($form_fields, $post) {   if (!array_key_exists('image-size', $form_fields)) return $form_fields;    global $_wp_additional_image_sizes;   foreach($_wp_additional_image_sizes $size => $properties) {     if ($size == 'post-thumbnail') continue;      $label = ucwords(str_replace('-', ' ', $size));     $cssid = "image-size-{$size}-{$post->id}";      $downsize = image_downsize($post->id, $size);     $enabled = $downsize[3];      $html = '<input type="radio" ' . disabled($enabled, false, false) . 'name="attachments[' . $post->id. '][image-size]" id="' . $cssid . '" value="' . $size .'">';     $html .= '<label for="'. $cssid . '">' . $label . '</label>';     if ($enabled) $html .= ' <label for="' . $cssid . '" class="help">(' . $downsize[1] . '&nbsp;×&nbsp;' . $downsize[2] . ')</label>';     $form_fields['image-size']['html'] .= '<div class="image-size-item">' . $html . '</div>';   }    return $form_fields; }
