How to get texture image url?

function getTexturesUrl(objNames) {
    objNames = retrieveObjectNames(objNames);
    if (!objNames)
        return;
    for (var i = 0; i < objNames.length; i++) {
        var objName = objNames
        if (!objName)
            continue;
        var obj = getObjectByName(objName);
        if (!obj)
            continue;
        var meshArray = obj.resolveMultiMaterial();
        var firstSubMeshMat = meshArray[0].material;
        for (var name in firstSubMeshMat.nodeTextures) {
            console.log(firstSubMeshMat.nodeTextures[name].image.currentSrc);
        }
    }
}

prints to the console urls for all textures used in object’s material
