Yeah, pins A4, A5 A6 and A7 can be a bit hard. That's because there is not really one standard for that. But most of the time the image in the listing is correct so you know the position before you buy.
And in the last batch of Pro Mini's I bought the serial header was backwards. Not a big problem, just turn around the USB-serial converter cable upside down as well. But just so you know. The text on the board actually tells you this so easy to spot.

I noticed that when I was looking at diagrams online earlier. The ones I bought have the same pinouts as the genuine Pro Mini in the reference. It's a good point to keep in mind though.
