Sorry this sat for two months without an answer. You were right: the page showed the count and gave you no way to open the folders.
Fixed today. Every vehicle page now has an "Albums" section listing your folders with a cover photo and a count. Open one and you get the whole folder, in your order. "Browse all photos" now goes there too, instead of paging through one photo at a time. Your '98 Legacy, for example:
https://www.supermotors.net/registry/20396#albumsNothing was deleted or moved. All 2,190 of your photos are exactly where you put them, across all 16 vehicles. The AI captions only fill in where you didn't write one, and your own captions always win.
If a folder still looks wrong, post the link here and I'll look.
