Popular culture portrayal of Buddha statues I have seen Buddha statues in western pop culture that portray an obese man as the Buddha. During my experience with Buddhism I have seen many more statues of the Buddha as a slim man, usually with one hand up, palm out.

Two pictures to illustrate:

Western pop culture portrayal:



More typical eastern portrayal:





I seek an explanation as to the reason for the difference in portrayal, if they are even of the same person.
The first statue is not Gautama Buddha (commonly referred to as "the Buddha"), but is Budai, a depiction of a loving and jovial Chinese monk, who is often considered a depiction of Maitreya, the next Buddha who will come into the world eons from now. 

Even some of the "skinny" Buddha statues may or may not be an image of Gautama Buddha. It mostly depends on the mudras (position of the hands) and the symbols used in the depiction. For example, usually Gautama Buddha has at least one palm facing inward with his fingers pointed towards the ground, but often today, commercialized statues sold in the west depict him in any kind of way because they do not understand the mudras and symbolism.
