Given that the sun is up at roughly the same amount, and at the poles the sun remains consistently up or down according to the season, I think we can rightly assume these two photos are taken at least approximately at similar times of the year.
Also, are you trying to insinuate that 100+ foot tall glaciers are somehow “seasonal?” Because they aren’t.
Glaciers actually do retreat and advance seasonally or on even longer cycles. Some have terminuses that move back and forth literal miles. One of the key indicators of climate change is the fact that globally, glaciers are retreating more than they’re advancing on average.
