Why are metaphase cells usually photographed for karyotyping?
(Thanks for your help!)

I don't actually know, but think about it logically.
Karyotyping is arranging the chromosomes in a standardized way that allows people to determine sex as well as chromosomal disorders easily.
When a cell is in metaphase, its chromosomes are all lined up, nice and neat, across one plane. It's the perfect time to see everything and get pictures of each chromosome to be able to arrange and observe them.
If this is a high school biology class question, as I assume, I bet all you're expected to do is use your insight after studying mitosis to be able to guess at this. Don't be afraid to guess; more often than not, you'll be right.
I hope this helped.

I would just like to confirm that the person above is correct. The cells are usually photographed for karyotyping during this stage because the chromatin is supercoiled and nicely arranged so. This makes for easy viewing and counting. Duriing other stages of the cell cycle, the DNA just looks like a dark messy circle.

By metaphase chromatin has compacted so when you do a chromosome spread it looks like the karyotypes we all see in the textbooks with the nice defined chromosomes.
