Programatically creating a product with image

Sorry but i have to reopen it, as it is related to ubercart and i have searched but the code for adding ckk images to not-ubercart nodes that i found in different forums/drupal issues wont work here.

The complete code is this:

$values['title'] = $product->nombre;
$values['type'] = 'product';
$values['body'] = $product->descripcion;
$values['uid'] = 0;
$values['model'] = $sku;
$values['list_price'] = $product->preciolista;
$values['cost'] = $product->costo;
$values['sell_price'] = $product->precioventa;
$values['default_qty'] = 1;
$values['shippable'] = 1;

$file_temp = file_get_contents(file_directory_path().'/productos/imagenes/prepro/'.$product->imagenes); //TODO andar
$file_temp = file_save_data($file_temp, file_directory_path() .'/productos/imagenes/'.$product->imagenes, FILE_EXISTS_RENAME);
$values['field_image_cache'][0] = array(
'fid' => 'upload',
'title' => basename($file_temp),
'filename' => basename($file_temp),
'filepath' => $file_temp,
'filesize' => filesize($file_temp),
'filemime' => mime_content_type($file_temp),
'data' => array(
'description' => basename($file_temp),
),
'list' => 1,
);
$rubro = obtener_rubro($taxonomies, $product->rubro);
$subrubro = obtener_subrubro($taxonomies, $product->subrubro, $rubro);
$values['field_product_taxonomy'][0]['value'] = $subrubro;
$marca = obtener_marca($taxonomies_marcas, $product->marca);
$values['taxonomy'] = array($marca);
$values['status'] = 1;
$node = node_submit($values);
node_save_noclearcache($node);

$product is a variable i get from a DB, and node_save_noclearcache() is just a copy of node_save function without clearing the cache to be more fast, but ive tried with normal node_save and it wont work.

The code works, because the only thing that wont get saved is the image.

$file_temp gets set correctly. Does anyone have done it?, if so, can you post your code?

forgot to active it, read above post

Well, can someone please help me?, you are all acting like mods, NOONE in this forum did something like this before?, noone can post his code or at least tell me WHATS WRONG with mine?...
