As Arnd said you should use vectors styled with externalgraphic and the select feature control to be able to select your markers and display a popup on feature selection. To be notified on feature selection register a listener on the layer's featureselected event. featureselected listeners receive an object with a feature property referencing the selected feature. This is shown in the example Arnd pointed you to. Eric
