Sorry to reply so many times to my own post.. but I kinda figured this out. Basically now I am setting the text property of each childnode after expanding to the WMS GetLegendGraphic request and then contatonating that with the text name of the node. Is there a better way to do this.. I am just using the expand event and then redrawing the entire childnodes with new icons.. can I do this before the nodes are even expanded?

(or before.. Or whenever as long as it shows). I declare my layernode like so - //Trails layerList layerList_Trails = new GeoExt.tree.LayerNode({ "layer": layer_Trails, "isLeaf": false, "checked": false, "enableDD": true, "cls": "rootnode", "singleClickExpand": true, "listeners": { 'checkchange' : function(node, checked) { // If a parent node is unchecked, uncheck all the children if (node.getUI().isChecked()) { node.expand(); } if (!node.getUI().isChecked()) { node.collapse(); } } }, "loader": { "param": "LAYERS" } }); Which is added to my root - layerRoot_Legend.appendChild(layerList_Trails); And then my treepanel var layerRoot_Legend = new Ext.tree.TreeNode({ enableDD: true, text: "All Legend Items", loaded: true, expanded: true }); var layerTree_Legend = new Ext.tree.TreePanel({ title: '', root: layerRoot_Legend, enableDD: true, applyLoader: true, rootVisible: false }); Except previously when I declared my layers individually I had put an <img> tag with the right layer next to each.. But now I am declaring them in groups like - //Trails Group var layer_Trails = new OpenLayers.Layer.WMS("<img src='http://localhost/WebService/Request.aspx?request=GetLegendGraphic&version=1.1.1&format=image/png&layer=Asphalt' alt=''/>Trails", "http://localhost/WebService/Request.aspx";, { layers: ['Onstreet_Bike_Route', 'Mountain_-_Stunt_Biking', 'Equestrian', 'Gravel_or_Shale', 'Asphalt'], VERSION: "1.1.1", transparent: true }, { isBaseLayer: false, singleTile: true, visibility: false, buffer: 1, ratio: 1 } But this only puts the image on the actual group name and I need it to be beside each legend entry when it is expanded. Is there a place somewhere I can stick this image tag and either hard code the layer name or have it be returned from the childNodes of the tree and get it to show this image beside each childNode?
