No code changes needed. Do:

layer = new OpenLayers.Layer.WFS( "Pics WFS", wfs,
        { typename: 'frumin:pictures', maxfeatures: 100 } ,
        { featureClass: OpenLayers.Feature.WFS.Pics, clientData: {
picUrlRoot: "http://frumin.net/pics/"}}
);

processXMLNode: function(xmlNode, clientData) {
    data.icon = new OpenLayers.Icon(this.layer.clientData.picUrlRoot + file, isize);
}

All options are copied to the layer, and the layer is accessible from
within the processXMLNode as this.layer.
