well..It seems that now the "magmag threads" are the same as the onesyou can find on http://nijibox.ohflip.com/futalog/jun/ so they have the same problem: after a short time the images start to disappear and you only got a 404 error!
So if you don't know a new system it's important to go on magmag or nijibox as fast as the 2chan thread die...

Ok, forget everything I've said above: I've discovered how it works just now!
And Mazoku already explained it in another post:
