Hi Amba,
Yes, I saw some alternative ways (on Armorama there is a topic for PhotoBucket). I've started an imgur account and uploaded some pictures there. Here are the final photos of the Pz IV L/70 to be remembered

Btw, I'm afraid that on one day imgur will also apply same payment rules, as Photobucket did... maybe an own homepage would be a solution?
cheers,
Zsolt
