TImageInformationEventArgs.ObjectIndex Property
Object index of the object being rendered. You can use xls.GetObject(objectIndex) to get the object properties, or you can use this property to attach an unique number in the sheet to the image filename. If the image is not an object (for example it is a rotated text) this property will be -1.
