no, the zip cart module always selects the largest size you have permission to view.
you'd have to modify modules/zipcart/classes/ZipCartPlugin.class to select a specific size.

very much thanks mindless i go to look that class bye ;)

I think this is the code:

		foreach ($resizes[$itemId] as $resize) {
		    $size = $resize->getDerivativeSize();
		    if (!isset($maxSize) || $size > $maxSize) {
			$item = $resize;
			$maxSize = $size;
		    }
		}

but for do that i think its necessary to add a new col or field in viewcart.tpl "Size" because i can select the same image in different sizes and this is 2 lines in viewcart.tpl.

Its possible? or very hard?

I think i need add a field "size" on the cart.

Where G2 store the information of the Cart? Can i add a field?

After (in viewcart.tpl) show that in a column.

you'll have to modify the cart module, but you can do that...

i think,in this source it's possible render image witdh function render of galleryDerivativeImage.class?

foreach ($resizes[$itemId] as $resize) {
$size = $resize->getDerivativeSize();
if (!isset($maxSize) || $size > $maxSize) {
$item = $resize;
$maxSize = $size;
}
}

what do you think this?

i can resize image width this:

$anchura=800;
$hmax=600;

copy($ruta,$nombre);
$archivoCop=basename($nombre);
$archivoCop="pp_".$archivoCop;
$datos = getimagesize($nombre);
if($datos[2]==1){$img = @imagecreatefromgif($nombre);}
if($datos[2]==2){$img = @imagecreatefromjpeg($nombre);}
if($datos[2]==3){$img = @imagecreatefrompng($nombre);}
$ratio = ($datos[0] / $anchura);
$altura = ($datos[1] / $ratio);
if($altura>$hmax){$anchura2=$hmax*$anchura/$altura;$altura=$hmax;$anchura=$anchura2;}
$thumb = imagecreatetruecolor($anchura,$altura);
imagecopyresampled($thumb, $img, 0, 0, 0, 0, $anchura, $altura, $datos[0], $datos[1]);
if($datos[2]==1){header("Content-type: image/gif"); imagegif($thumb,$camino[0]."tmp/".$archivoCop);}
if($datos[2]==2){header("Content-type: image/jpeg");imagejpeg($thumb,$camino[0]."tmp/".$archivoCop);}
if($datos[2]==3){header("Content-type: image/png");imagepng($thumb,$camino[0]."tmp/".$archivoCop); }
copy($camino[0]."tmp/".$archivoCop,$original);
unlink($camino[0]."tmp/".$archivoCop);
unlink($nombre);
