 * The getimagesize function will determine the
 * size of any supported given image file and return the dimensions along with
 * the file type and a height/width text string to be used inside a
 * normal HTML IMG tag and the
 * correspondent HTTP content type.
 *
 * getimagesize can also return some more information
 * in imageinfo parameter.
 *
 * @param string $filename This parameter specifies the file you wish to retrieve information
 * about. It can reference a local file or (configuration permitting) a
 * remote file using one of the supported streams.
 * @param array $imageinfo This optional parameter allows you to extract some extended
 * information from the image file. Currently, this will return the
 * different JPG APP markers as an associative array.
 * Some programs use these APP markers to embed text information in
 * images. A very common one is to embed
 * IPTC information in the APP13 marker.
 * You can use the iptcparse function to parse the
 * binary APP13 marker into something readable.
 *
 * The imageinfo only supports
 * JFIF files.
 * @return array Returns an array with up to 7 elements. Not all image types will include
 * the channels and bits elements.
 *
 * Index 0 and 1 contains respectively the width and the height of the image.
 *
 * Index 2 is one of the IMAGETYPE_XXX constants indicating
 * the type of the image.
 *
 * Index 3 is a text string with the correct
 * height="yyy" width="xxx" string that can be used
 * directly in an IMG tag.
 *
 * mime is the correspondant MIME type of the image.
 * This information can be used to deliver images with the correct HTTP
 * Content-type header:
 *
 * getimagesize and MIME types
 *
 *
 * ]]>
 *
 *
 *
 * channels will be 3 for RGB pictures and 4 for CMYK
 * pictures.
 *
 * bits is the number of bits for each color.
 *
 * For some image types, the presence of channels and
 * bits values can be a bit
 * confusing. As an example, GIF always uses 3 channels
 * per pixel, but the number of bits per pixel cannot be calculated for an
 * animated GIF with a global color table.
 *
 * On failure, FALSE is returned.
