Dynamic image does not appear!

Hey everyone,
Got a bit of a prob here, hope you can help.

I got a XML file where addresses to images are defined.
Then I got a movieclip on my main timeline named “imagecontainer”.

Now when I try to load the image into the movieclip with this code:

xml blablablablabla
curr_item.img = node_xml.firstChild.attributes.img; 
more blablabla 
curr_item.onRelease = function();

The problem is that the trace function gives the correct image address, and when I put a graphic in the movieclip where the image must load, the graphic disappears, so I think the image actually loads, but it isn’t displayed.
Anyone got an idea?

Hope so…
