This photo is a fake. I have calculated the math here. There are around 18 men lifting a block here. Each block in Giza pyramid weigh around 2.5 tonnes. An average man can lift around 50 KGS. When you put in the numbers, 18 men can lift only 900 KGS. So obvious fakery.
Actually, 2500/18 is only 139kg. That’s a lot, but it’s less than what some people do today
edit for those taking this serious: that block is way heavier than 2.5 tonne. Sandstone has a density of about 2.323 tonne/m3. This block looks about 8 meters long, so 8x8x8x2.323=1.187 kilotonnes
But regular workers back then didn’t understand what those weight numbers/hieroglyphs meant, so they just picked it up unaware it’s way too heavy to do so.
The photographer was giggling at them & about to explain how heavy the blocks are - but doing so a lot of workers would be immediately pancaked.
