Catching thumbnail images

File: /include/inc_lib/imagick.convert.inc.php (V1.4 r287)

Function:

// build thumbnail image name
function get_cached_image($val, $db_track=true, $return_all_imageinfo=true) { ....
	// Return cached thumbnail image info
	// $thumb_image_info[0] = Name, 
	// $thumb_image_info[1] = width, 
	// $thumb_image_info[2] = height, 
	// $thumb_image_info[3] = HTML width & height attribute


Example call: article thumb in front.func.inc.php ~ Zeile 1192:

$thumb_image = get_cached_image(
array(	"target_ext"	=>	$article["article_image"]['list_ext'],
	"image_name"	=>	$article["article_image"]['list_hash'] . '.' . $article["article_image"]['list_ext'],
	"max_width"	=>	$article["article_image"]['list_width'],
	"max_height"	=>	$article["article_image"]['list_height'],
	"thumb_name"	=>	md5($article["article_image"]['list_hash'].$article["article_image"]['list_width'].$article["article_image"]['list_height'].$GLOBALS['phpwcms']["sharpen_level"])
));
