The cover article from the June 10, 1916, issue was written by one of the foremost experts on airships and aviation before, during and after World War I, Baron Ladislas d'Orcy.
The information about the capabilities of the airship is noncommittal; the location of the photographs is deliberately vague:
“The dirigible represented herewith is one of Great Britain's small scouting airships, which have been provided for in the new British aerial construction program for 1915-17. This program is said to comprise the laying down of 50 airships of both the rigid and non-rigid types, the construction to be completed within two years.” [In reality approximately 158 of this type were made]

“Although their work has been less spectacular than the operations of German Zeppelins, the non-rigid and semi-rigid airships of Great Britain and France have proven very useful for night raids on enemy encampments, and, in connection with naval warfare, for harbor defense and coast patrol work. According to the Echo de Paris, the mobile forces of every French naval port now comprise, in addition to destroyers and submarines, two small non-rigid airships. These are chiefly used for detecting enemy submarines, and are said to have given an excellent account of themselves.”
One of the satisfying parts of being a historian is being able to look back on such articles and fill in the details that may have been removed or discouraged by the military censors of the day.
These “submarine scout” or “sea scout” airships begun construction in March 1915 by the British Royal Naval Air Service as small, cheap, easily manufactured, easy-to-fly airships for anti-submarine work. A relatively small lifting blimp carried slung below it the stripped-down fuselage of an aircraft carrying engine, pilot, observer and usually a machine gun and a few small bombs.
The version shown seems to be powered by the fuselage of a B.E.2c aircraft—a fighter/bomber designed early on in the war. The tube that runs from just behind the propellor goes up into a ballonet (air bag) inside the airship; it was designed to be filled with slightly pressurized atmospheric air to keep the balloon inflated and rigid.

The story lists two areas of operation, the “Balkan front” and “a Mediterranean base” but the locations shown may be the air bases on the island of Lemnos and on the Greek peninsula of Kassandra. The airships were most likely used for anti-submarine patrols in the Aegean Sea and the Mediterranean, defending the Allied armies (and their long, vulnerable supply chains) near Salonika, Greece (now called Thessalonika). Allied forces, most of them redeployed from the failed Gallipoli campaign, had landed in Macedonia in Greece near Salonika in 1915 and struggled until 1918 against the combined forces of Bulgaria, Germany and Austria-Hungary.
An interesting blog written by Mark Clayton, senior curator at the Queensland Museum, Australia, goes into a little more depth about this intersection of history and aviation: https://blog.qm.qld.gov.au/2015/04/24/gallipoli-from-above-the-clouds/
