Brief update for everyone:
Photo uploading has begun! Thank you to weisling53 for providing the first one. I'm continuously working to improve the interface to make it quick and easy. I'll be on vacation next week, so less progress then. Thank you, again, for everyone's support. I'm glad to be working on a project that many will find useful and interesting.
AI would be great for this problem! Too bad I don't know much about coding with that yet. One day.
For now, they will need to be manually reviewed. As stated, I'll be seeking moderators at some point in the future.
Searching by special livery will be pretty easy. But it won't be in a nice drop down... you'll have to type it out.
