The age of a thread is irrelevant. Ther eis still enough space in the other 2 threads for new pictures.
When you post a new pic in an old thread it brings it up to the front of the board so people will see there are new pics.
So today I'll spend my time filling this thread with pics just to get rid of it.
Because we don't need a new thread.
Also, almost everytime there are multiple threads they are filled with reposts that are already in the other threads.
