Google is reported testing a new online storage tool called, "Cloud Picker". It appears that the tool is connected somehow to Google Apps, Docs, and Sites, and was presented to users when they tried to insert a file or image into a Google site. When they tried to embed the file, a "Google Cloud Picker" window opened and asked users to log-in to their Google Accounts.
Many users flocked to the forums (here, here, here) because Cloud Picker wouldn't work with any Google Apps account. When used with a regular Gmail account, Cloud Picker brought users to a Google landing page with "Profile" and "Personal Settings" at the top and "My Products" at the bottom.
Another user posted an image above of Cloud Picker, and it appears that it's a new storage product that allows users to organize and search photos, documents, videos and more that are stored in the cloud.
