They both contain 23 pairs of homologous chromosomes (and... yes as Luis suggested the first one is male and the second one female).
In Figure 1 each chromosome is composed by 1 chromatid, while in Figure 2 each chromosome is composed by 2 chromatids. This is probably because the two pictures were taken at different stages of Mitosis.
In Figure 1 the picture was taken probably in anaphase, while in Figure 2 was probably taken in or before metaphase.
You might want to search the internet to check the **difference between chromatids and chromosomes** and to read something about the **cell cycle and mitosis**.
