According to specification and function description, Canon 70D and Canon 6D shall be able to upload photos to internet album with Wifi. I succeed in controlling camera shot from my android smartphone, but always failed to upload photos to albums. The general discussion on Google search result lead to "We can only upload photos to Canon Image Gateway but not facebook", or others.
In fact, affter my installing Canon EOS Utility software from attached EOS DIGITAL Solution Disk, I found an additional function "Set Up Web Services". I think that it shall be the shortcut to achieve the function, but I always failed with error message: "this function cannot be used because your country/region is not supported by the Canon Image Getaway service".
After reading many documents from Canon, I cannot find any solution to solve it.
Finally, I found the way myself, it means: I can upload photos from Camera to Facebook, Twitter, Google Drive, Youtube, Flickr, Canon Image Gateway, and mail to friend.
