How can I copy many large hi-res photos directly from iPad to cloud storage via WiFi and then manage them? What's a good method to copy lots of high resolution photos from my iPad using WiFi directly  to some sort of cloud server without having to use a Windows or Mac computer as an intermediary? Plus, once they're in the cloud, I'd like to delete the originals from the iPad and then use the iPad to organize/manage the photos on the cloud server: sort them into folders, rename them, and view them, etc. 

I think I can use Dropbox for much of this but is there anything more efficient for managing lots of high-res photos? I think iPhoto and Adobe Revel are only useful if your photo library is based on a desktop computer - I want to avoid that step.
Isn't that exactly what the Photo Stream Feature is good for? It snycs all images directly into the iCloud. Yes it would also sync them to all devices, but I guess that's optional.
