Original Note:
Unless an old picture was taken at very low tide, it is easy to take a modern picture that matches the same sea level. Global mean sea level rose about 0.20 m (8 inches) from 1901–2018 https://www.ipcc.ch/report/ar6/wg1/downloads/report/IPCC_AR6_WGI_Chapter09.pdf The difference between high and low tide in the open ocean is about 0.6 m (24 inches) https://www.infoplease.com/encyclopedia/earth/geology-oceanography/info/tide/the-magnitude-and-effects-of-tidal-ranges
