To set default value, you got to use the dialogDefinition event to modify dialog fields (see this answer: How do I programatically set default table properties for CKEditor?).

To change the value dynamically:

CKEDITOR.replace( 'editor1', {
    extraPlugins: 'devtools', // useful for dialog development
    on: {
        dialogShow: function ( evt ) {
            var dialog = evt.data;

            if ( dialog.getName() == 'image' )
                dialog.setValueOf( 'info', 'txtUrl', 'http://foo.com' );
        }
    }
});
