Can you offer any more details? I have used the latest version of PowerCMS with no issues at all.
But, I cannot help based on the vagueness of the issue your reporting. When you say photo upload problems, are you referring to the advanced file manager? Is the issue with the actual CMS or with how it is being displayed on the front end?
Also, I am not sure about the reasoning you list for not posting a URL. The idea that Google will pick it up and list it as a problem site is just not how the system at Google works. So post it and let us have a gander and, perhaps, someone here can offer a solution.
