There are a few places in the database where you can store images. The first place is in the vehicle record. You can upload your favorite picture to remind you of just how good that vehicle looked when you finished the restoration. The second place is with an event. You can store a picture of that piston with a hole in it, or the sunset in the hubcap, or the gang at the campsite knocking back a few beers.
Motocron Images exist only to aid your memory and your documentation. There are great options out there for photo albums and blogs if you want a more social and extensive web presence. Check out the Classic Velocity Blog for an example.
