When I place orders online, I know what I am looking for/getting, so the presence of images (or the lack thereof) is really unimportant. This is especially true when the seller is trusted (as Mikko is). I don't see the missing images on his site as reflecting a lack of effort or anything so much as presenting an image of "if you know, you know." With noise, how can you really go wrong with that?
Looking over recent purchases, has there really been that much you have bought as a result of seeing a picture? For me, recognizable names/connections (through labels, projects, etc.) are a much bigger determining factor.
