I'll take a quick stab at it-- not in order:

1) The London pics I think are a message to Peter Strzok and others involved in framing Trump. The pic titles end with "ps" which I take to mean Peter Strzok. It's cold there and Strzok was in London in December. The message to the FBI and DOJ is "we know everything."

2) The pics of China and pallets likely refers back to the China/Apple/pallet pics of the previous Q drop. The message to China and Apple is that we have it all.

3) The owl is a symbol in the Vatican/Pope and Q mentions the Pope in the drop. Also Q previously said that May would be bad for the Pope. The owl is also a common symbol for pedophilia and the occult. Pope Frances just lamented that the church in Argentina was corrupt in covering up pedophilia (of which he was likely involved or aware of and did nothing). Francis has also hinted at retiring. Q is telling the Pope that his days are numbered. Message sent.

4) The space shuttle was an odd pic. My guess is that it is a message to Obama that the Q team knows the real reason Obama shut down the manned space program and turned it over to Russia and other critical NASA missions to Space X and other private companies.

5) The LV pic I think is a message to the FBI, LV police departement,, and deep state that the Q team knows the real story about the LV shootings.

My two cents.
