Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
The Picasa 2 channel allowed me to view my extensive slide collection on the TV. After Google apparently bought Picasa, they dropped supporting Picasa 2. When I tried to re-activate Picasa 2, I was given a code and told to go to a Google Device website and enter the code (not unlike what is done with other Roku channel activations) and then go to TV (Roku) and Picasa 2 would now be activated. Tried this several times with new codes, but it never activated. PLEASE HELP!
For more information about that channel's features and functionality, you'll want to contact Picasa (Google) support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
