Hi mate,
I've just added HS30 00894, but if you go look at the way this car is included you'll notice it has a link to an album, this is actually easy enough to do. What I am currently thinking is all the cars I've collected so far can be documented with their specifications in a regular CSV file (like a spreadsheet) and I'll maybe have relational sheets for owners details and history etc..
The images can be stored locally in the gallery, each album will be given the name of the chassis ID and when I get a chance I'll figure out how to integrate the gallery and csv data into a custom module for this site. So that basically the register is part of the site. However the good thing about storing the data in a CSV is that it should be easy enough to transport it and join it with the new database when ready. The good thing about this approach is we can work out what fields / schema we want i advance before writing anything permanent.
Still there is much manual work in maintaining it, but it's my hope that members will eventually be able to contribute information with the need for me. So we can open it up to later S30Z's like 260z's and 2+2s etc..
That was a long winded way of saying currently all the images are hosted on my own Google Photos account, but I plan to move them to Auszcar's native gallery function.
