Hello,

i'm using PSWebServiceLibrary.php class to access to product images, the code is this:

 

$opt['resource'] = 'images/products';

$opt['id'] = 35;

$img = $webService->get($opt);

 

I get a 500 error, there is something i miss? (i know i have to whatch server log but are empty).

Any idea is appreciated, thanks!
