Distribution fag, here.
May be late to the party, but can tell you these things for certain:
1) The pallets are CHEP pallets. They are never sold only rented. They are generally used for loads greater than 2000 lbs. This supports the idea that, whatever the load is, is heavy.
2) Strapping tape has been used under stretch wrap. This is an extraordinary step which confirms the boxes are very heavy and subject to high shifting risk.
3) The load has been placed on a "lipped" slip sheet on top of the CHEP pallet. This tends to indicate either a) the load is subject to damage from PIT forks and needs extra protection around the base, b) the load needs extra protection from shifting due to its weight, or c) both.
4) The load consists of a 6-tier TI-HI and has a face of 12 cartons. Because it rests on a standard North American sized pallet (3' x 4',) we know the carton's face is 18" wide (2 wide x 6 high.)
5) The cartons appear to be 12 or 13 inches tall. Each pallet appears to be 60 cubic feet.
6) Because the facing is a "tower stack" and the layers are not alternated, we know the depth must be evenly divided by 4 feet (i.e., 4 x 12" cartons, 3 x 18" cartons, 2 x 24" cartons.)
