They get theirs from the real scientific literature and, unlike creationist sources, they cite it accurately.
There is a wide variation in the skulls of homo sapiens, and this includes cranial capacity and bone structure. This is not surprising since there are wide variations among different people across the globe. Many of those skull show could very easily be human.
But you just said a post or two ago it was a bunch of ape skulls.
To try and claim that they are transitionals is quite amusing.
Then why are you dodging? Where are the apes and where are the humans. Why don't creationist authorities agree with each other? Why does the fossil record show creatures with the mix of features shown becoming less and less like a chimpanzee (our nearest relative and the skull at the upper left) and more and more like a modern human (the skull at the bottom right?)
Darwin's theory predicted that such a progression of beings must once have lived. Creationism just scoffed. They turned up. How did that happen?
Same thing happened with the land-animal and amphibious ancestors of whales. Evolution said they must have existed. Creationism scoffed. They turned up.
The same thing happened with the ancestors of birds. Creationism scoffed. They turned up.
How does that keep happening? How is it all amusing? Is it because nobody can make you see? Is militant ignorance science?
