You have to understand that that is done on all cosmetics (retail) websites. It is just too expensive, wasteful, and time consuming to actually take pictures, crush, etc. every single product. That's why most products are the general "finish" picture, with the color photoshopped on top of it. Like most Amplified Cream lipsticks, and Lustre eyeshadows are the same image, just different colors. That's why one should always take these facts into account when ordering online.
Specktra is a great resource to use when deciding on ordering colors, since many members go out of their way to post swatches, and describe products in depth. =)
