Image not found to default image at Import Xml

Hi all,

I have a problem when importing an xml-file.

When an image cannot be found, indesign asks to select the file.

I want to disable this and place a default "no_image.jpg" instead of the image.

I don't want to sit and select the default image for every image in the xml that can't be found.

I'm using Adobe indesign CS4 with javascript.

Can someone point me in the right direction?

Thanks in advance.

Glen
