You're not wrong to assume 4chan first though. By sheer size, 4chan's file output is going to dwarf all the combined images of other vichan IBs. It is good to assume that site first when trying to fine an image's origins. I mention it just in case you come across the rare unix filename that doesn't lead to 4chan, so you at least know to look at other IBs instead of having to give up.
