Prototype Ajax.Updater Response OK, but not showing up in FF. working in Safari

I've got a quite strange problem here.

I'm calling some simple code via Ajax.Updater:

new Ajax.Updater('load','http://myurl.com/demo.pl?key=demokey&param1=xyz&param2=abc',{
method:'get',
onComplete:function(transport){
alert(transport.responseText) } });

which gets some code like this:

<img id="2009_04_15_1239786246"
    src='../pv/100/2009_04_15_1239786246-01.jpg'
    border="1"&开发者_开发问答gt; <img
    id="2009_04_15_1239786066"
    src='../pv/100/2009_04_15_1239786066-01.jpg'
    border="1">

... and so on

This code shows up in my firebug console as my server response, so everything should be fine. No errors here at all. Works fine in Safari 4.

Firefox 3.6, according to Firebug, knows there is a response, but it won't show a thing in my div 'load' and the alert(transport.responseText) is also empty.

I have no idea what could be the problem here.

You are using numbers in the beginning of of your <img> tag ids, which is not correct and might make some browsers to turn against you. Use some other leading character in those ids.
