/**
 * i.php: Zenphoto image processor
 * All *uncached* image requests go through this file
 * (As of 1.0.8 images are requested directly from the cache if they exist)
 ***************************************************************************
****
 * URI Parameters:
 *   s  - size (logical): Based on config, makes an image of "size s."
 *   h  - height (explicit): Image will be resized to h pixels high, w is calculated.
 *   w  - width (explicit): Image will resized to w pixels wide, h is calculated.
 *   cw - crop width: crops the image to cw pixels wide.
 *   ch - crop height: crops the image to ch pixels high.
 *   cx - crop x position: the x (horizontal) position of the crop area.
 *   cy - crop y position: the y (vertical) position of the crop area.
 *   q  - JPEG quality (1-100): sets the quality of the resulting image.
 *   t  - Set for custom images if used as thumbs.
 *
 * 	 Cropping is performed on the original image before resizing is done.
 * - cx and cy are measured from the top-left corner of the image.
 * - One of s, h, or w _must_ be specified; the others are optional.
 * - If more than one of s, h, or w are specified, s takes priority, then w+h:
 * - If none of s, h, or w are specified, the original image is returned.

W czym rzecz? Ten kod tworzy miniaturki w locie, ale... Dla pewnych zdarzeń zwraca je ( w FireBug są widoczne i w FF jak się da 'Odśwież obrazek' ), ale dla HTML nie, dlaczego tak się dzieje? Jak to można zmienić?

PS. Komentarze można usunąć.

Co znaczy "dla HTML nie" ?
Że w źródle strony nie widać zawartości obrazka, co jest raczej normalne (obrazek to kod binarny a nie tekstowy) ?
W kodzie powinno wypluć

I tak robię, wywołuje i.php z odpowiednimi parametrami, ale podczas edycji miniaturki ( kadrowania ) problem się pojawia taki, że FireBug zwraca nową miniaturkę, ale w kodzie HTML jest jedynie link z alt, po najechaniu na element FireBug'iem i dany element <img> obrazek się pokazuje. Sam obrazek wypruwam w ten sposób:

		header('Cache-Control: no-store, no-cache, must-revalidate');  // HTTP/1.1
		header('Cache-Control: pre-check=0, post-check=0, max-age=0'); // HTTP/1.1
		header('Last-Modified: '.gmdate('D, d M Y H:i:s', filemtime($imgfile)).' GMT');
		if (@strtotime($_SERVER['HTTP_IF_MODIFIED_SINCE']) == filemtime($imgfile)) {
			header('HTTP/1.1 304 Not Modified'); 
		}
		header('Content-Type: image/'.$suffix);
		@ob_clean();
    	    	@flush();
		readfile($path);

Wszystkie obrazki się przeładowują, dla wszystkich zwracane jest istnienie pliku ( nowej miniaturki ), ale czasem nie wyświetlają się mimo ich istnienia. Co może być powodem takiego zachowania? Przypomnę, że lista miniaturek jest generowana w 'locie' podczas stworzenia element <img> z odwołaniem do pliku PHP, który powinien je zwracać.

Pomożecie? Aktualny kod do zwracania miniaturki to:

Chodzi ci o to że masz 100 obrazków w galerii i powiedzmy 20, 30, 40, 50, 66, 90, 95 się nie wyświetla mimo że w kodzie HTML masz ustawione
<img src="i.php?i=obrazek&w=200$h=100" alt="Nazwa obrazka" />
Jeśli tak to może serwer po prostu nie wyrabia z tworzeniem x miniaturek na raz.
