As you probably noticed we moved to a new server yesterday and unfortunatelly not all pictures were transferred correctly, so you can only see 120px thumbnail instead of some of them. It is quiet large issue because almost a half of the images is affected.
The solution is fortunatelly quiet simple - we will upload these pix again. We are now working hard to make it happen ASAP - give us a day or two and everything should be fine again. We are very sorry for the inconvenience...
