[OpenLayers-Users] WFS Layers, Markers, Popups

[Eric Lemoine]

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
