depending on whether you want to open the image in the 'category view' or in the 'detail view' with the pop-up box, you have to change the setting in the Configuration Manager either in the tab
Category View -> General Settings -> Entering Detail View
or in the tab
Detail View -> General Settings -> Open Original Image
