There's also an alternative drilldown where you only need the style #, and you can get three views usually, but only in one color. These are the pics Coach uses on their website when you go to the bag details -- one mod shot, one regular, and one from the top with the lining showing.
Here's are the links -- all the same except for the number after the a -- use a 1, 3 or 9. Sometimes not all three pics are available when the bag is pretty new, 3 seems to be the first one to show up if you're looking at new styles

Sometimes I just keep plugging in style #s sequentially to see what comes up. Right now the bags are in the high 19000's and low 20000's, like 19899 and 21224. It's hit or miss, Coach does leave big gaps.
