Hi,
according to the show off thread, wouldn't it be nice, if the designs are also viewable within like a picture gallery in the users profile? Or a sub-forum, where the users can drop of the new pictures individual as thread
Not all of my designs I will present in the show-off thread... or I do a little change which looks better but I didn't want to make an extra post for.
The first thought about a picture gallery connected to the profile I feel good about it, so the user is able to swap pictures or collect old and new designs.
To limit the storage space a little bit, it can be for example 3 pics for a design and 3 or 4 designs for a car.
In sum this could be (in the moment) round about 1000pics per user (if each user makes 4 designs with every 3 angle views), but the most of them surely use less then this number.
