[Users] geoext.popup - position problem

[Andreas Hocevar]

Hi,

you can add events to the img. Here is a snippet from my library, used in the context of an OpenLayers popup (where auto-sizing also fails if images tags don't have a width and height attribute or are not preloaded):

var image = new Image();
image.src = "";
image.onload = function(){
// create and display the popup
popup = new OpenLayers.Popup.FramedCloud("popup",
    new OpenLayers.LonLat(pos.x, pos.y),
    new OpenLayers.Size(250,150),
    "<div class='popupHdg'>" + feature.attributes.text + "</div>" +
    "<img src='" + feature.attributes.thumb + "'/>" +
    "<a class='popupLink' target='_blank' href='" + feature.attributes.pdf + "'>PDF</a>",
    null, true, function(){
        popupControl.unselect(feature);
    });
    feature.popup = popup;
    map.addPopup(popup);
};
image.src = feature.attributes.thumb;

-Andreas.
