Actually, Google Android can achieve the same function through Google+ Instant Upload and Picasa Sync to Web.
Here is how to do that:
First, install Google+ on your Android phone .
Check Turn on Instant Upload. You can also set when to upload photos (like WiFi only).
To automatically push to photo from Google+ Instant Upload album to your PC or Mac, you need to install Google Picasa.
Select the Instant Upload album, then switch the Sync to Web on.
The best part is: the changes you made to the photos (like add Caption, Comments) in Picasa will be automatically sync to Google+ Instant Upload Album too. The other way works too (Changes made in Google+ Instant Upload Album sync to Picasa).
If you do not want to wait the sync happens automatically, you can right click on Instant Upload album in your Picasa and select Online Actions > Refresh Online Status
If you want to have a look at where the photos are stored on your desktop, you can right click on the Instant Upload album and select Locate on Disk.
