Well it's not a good sounding start is it - I can tell you one thing for certain is that we are always accessible, with an emphasis on the Help page and email support. 

The other 8 photos are fine and they say hello from the Matrix - there is sometimes a delay between approval and coming online, depending on the workload. We do our best to juggle everything with reviewers, system resources, and upgrades, while avoiding imposing direct limits on uploads.     

As for the forum, I am concerned you would plan to avoid it since (IMO) it's a pretty good neighbourhood, not as busy yet as MSG but one day maybe.  I will fire up Opera and see what the issue may be. Again it's maybe better to write support directly and we can get the details of software versions etc.

I had a similar problem. Some of the images were not online because their thumbnails got mixed with other photographers' images during upload. I notified Zymmetrical, and they told me to upload them again. They were able to tell me which images were stuck, for about half of them. I uploaded those as I didn't bother figuring out what other images were not online since I would have to go though all of approved and rejected images to  do that.

After uploading, some previously approved images were rejected. The explanation was that they were not originally reviewed by a proper reviewer.

Apparently, the thumbnail mix up is not supposed to happen anymore as they performed server upgrades.

Well this is why we prefer to deal with technical support issues directly -  there is no issue with your 8 photos Xalanx, other than the system simply processes them as fast as is possible. There's no mystery involved, sometimes things slowdown during a surge of uploads - again we are doing the best we can while not imposing upload limits.
