u cannot get the image url from the imageview...infact u will have to use the alternate. For example u might be saving the urls for the imageview in some array...u need to get the position of the imageview clicked and using that position u can get the url of the clicked image...if u r using listview/gridview it is very easy to get the position but if not, u can set the pos as tag of image and retrieve the tag that will specify the position.

if u need help feel free to ask...
