Can you post a copy of the XML that you are actually receiving from
the service?
if you put
trace(XML(evt.result).toXMLString());
in your
httpService_result function, you should get a look at the XML that is
being sent to your application from the web service.
At a glance here, my guess is that the "@" may not be needed, or that
you are just asking for the wrong variable. You use the @ symbol to
specify XML attributes, if you omit the @ symbol, you are specifying
XML elements. So the answer depends on XML that you are receiving. If
I had to guess, I would guess you probably need
data.url
or

[EMAIL PROTECTED] as well as [EMAIL PROTECTED] But I am not

I am doing wrong, it also prevents the gallery 404 error message
appearing anymore...
Any help would be greatly appreciated.
