How to chose product image size using PS webservice (PS1.7.4)

[DARKF3D3]

I'm using a php script to show product images on a PS website, the problem it's that I can't find how to set the image size.

The script actually it's showing images in full size, but they're too big, so i would like to use a smaller PS size, like home default.

This is the code used to get the image path:

$result['product'][$key]['default_image_link'] = getProductImage($product['id'], $product['id_default_image']);

Do you know how to do this?
