Here's a boring overly-logical not-the-least-bit-funny explanation -- by random chance, half (or more) are _initially_ posted with photos from the drive side. But those bikes sell faster, so over time, more of the remaining ads feature NDS photos.

ok, this is interesting... I just pulled a 26.8 seatpost out.
Looks like the lug ears *may* be squashed together more than they should, but will come back to this later today. Meanwhile, am I wrong to think that this is strange for this bike? Surely a 27.2 for the usual 531, or at least a 27.0 for older straight-gauge 531?

so here's top of the seat tube. my (unseasoned) eye says this looks pretty kosher, and the opening is undamaged and seems pretty round. But if old Treks are supposedly all 27.2, why on earth is 26.8 a snug fit here?

Regarding the fork issue, pull it and see what brand of fork it is. My 82 412 was made late in the model year. The fork in it is a Tange. It must have been a running change to get around the problem.

so I'd be looking for Ishiwata = possible problem, Tange = improved/safe(r) design?

It should be 27.2.

incazzare.
Roughly 90% of people are right handed, so when walking a bike they tend to grab the bike with their right hand, and walk on the left side of the bike. They will also mount and dismount from the left side.
So when taking a photo, the walk it over to a wall, and lean it against it, all while standing on the left side.
Hence, we get mostly non drive side pictures.

Here's my theory on that.

another theory, and one that's easier to disprove! -- maybe the distribution of photos is not what we *think* it is. Maybe drive-side is the clear majority because sellers are, on the whole, sensible, logical folk. (theory already struggling). But our own seething frustration at the hidden clues, unhelpful angles etc., makes the experience of a non-drive side photo so much more memorable and so we overweight the experience and feel these photos are the majority?
logical sellers? nah. lostarchitect's sounds more plausible.

I would say it's because average Joe bike seller doesn't know that potential buyers are interested in the components. They are thinking about the frame only, so they take a picture from that side. The drive side will be covered up by..........components.
