After you click on images to ENLARGE them, you may find they automatically size smaller in your browser's window making them harder to view. The auto sizing is your browser's way of keeping images entirely within the screen size you have set. Move your mouse pointer to the bottom centre of the pic and you will see an options panel appear. There will be a small square box next to the large X, which will have a pointer arrow sticking out of it. If it's illuminated, it means the pic you're viewing can be enlarged, so click on this box and the pic will EXPAND and open to its normal size. You can then grab the pic with your mouse (hold down left mouse button) and move it around to look more closely at various parts of the photo.
