Since today photos from Panoramio up to ID 13,760,000 are included in Google Earth, this means almost one million new photos added.
The date of the next update will be around October 24th and will include photos reviewed up to October 10th. However we are testing more frequent updates and maybe you will see your photos earlier in Google Earth. For the moment we are testing bi-weekly updates and gradually the delay will be reduced. Hopefully in few weeks we will have daily updates, so the last reviewed photos will take only one day to appear in Google Earth.
