Hi Samuel, I use attribution (thanks to Phil for the idea), here you have a good example: http://stackoverflow.com/questions/5539633/adding-a-absolutely-positioned-div-to-the-bottom-of-an-openlayers-map/5568762#5568762

The layers I display are therefore color graduated. I would like to add a color scale to the map to make the correspondence between the color and the forecasted concentration or rain intensity. Since the application will be used in full-screen mode, I would like the legend to float over the map like the zoom controls. The WMS GetCapabilities does list styles from the layers and contains LegendURL elements with links to the actual resource. "Format/WMSCapabilities/v1_1.js" defines the function GetLegendGraphic, but it's not used anywhere else in the OpenLayer(version 2.12) code. What would be the best way to add the legend over the map? I could copy and modify "Control/Attribution.js", but is there a better way to do this? Also, ideally I would like to make a link with the currently displayed layer and the retrieval and display of the legend.
