Sample pop-up page. These are configured to open in a new window or tab. To return to where you were simply close the window or tab. This may work differently on a mobile device but the principle is the same. My ancient smart phone uses the return arrow. NB: This was photographed on my home made macro-rig (see assets) and although obvious in this case, the 15px maroon dot next to any image reference, is my declaration the image was not shot in the natural environment. The 15px green dot is my declaration the specimen was not sourced specifically in the Goyt Valley.
