We have to find a solution for series indeed.
The structure of the new site with multiple pictures for a vehicle will already help, as extra pics won't be in comments but linked to the vehicle itself, that will allow then to automatically generate vehicle listing per episode, as not only the main pic's episode will be known, but all pics' episodes.
That will not be directly for version 3 of the site, but will quickly arrive in the updates we'll continue to do.
