PHP show_image函数代码示例

 /**
  * Get the markup to show an image thumbnail
  *
  * This function is a wrapper for show_image() that returns what show_image() would
  * normally simply output.
  *
  * @param mixed $image An image object, image ID, or array of image values
  * @param boolean $die_without_thumbnail Echo nothing if no thumb available? (default behavior 
  *                                       is to make link to full-sized image if no thumb available)
  * @param boolean $show_popup_link Wrap image in link that pops up image popup?
  * @param boolean $show_description Place the image description (i.e. short caption) below the image?
  * @param string $other_text Text to use instead of image description
  * @param boolean $textonly True sets function into textonly mode, which instead of outputting
  *                          image markup outputs a text description linking to image
  * @param boolean $show_author Output the value of the author field below the description?
  * @param string $link_with_url Wrap the image in a link to this URL instead of to image popup
  * @return string XHTML markup
