Watch a folder and send images to your Google Plus Instant Upload album

The bash script below will watch the PicasaWeb folder in your home directory for new files. When a new image is dropped in the folder it is uploaded to the Google Plus Instant Upload Picasa album. After the upload is complete the script launches your browser to your Google Plus photos. It also starts a Gwibber widget. If you want dent, or tweet the image URL.

Prerequisites and Instructions

• You should be running Linux. I am using Ubuntu
• You need the command inotifywait. On Ubuntu I installed it via sudo apt-get install inotify-tools
• You must have a Picasa account
• Install libnotify-bin for the notify-send command
• Install Google CLI
• Create "PicasaWeb" folder in your home directory mkdir ~/PicasaWeb
• Copy and paste my bash script above into a file. I named mine PicasaWebMonitor.sh.
• Make PicasaWebMonitor.sh executable chmod +x PicasaWebMonitor.sh
• Start the bash script ./PicasaWebMonitor.sh.
• Create some images and save them to the ~/PicasaWeb folder
• Avoid using spaces and special characters in your picture file names. The Picasa Web direct URL will be encoded and won't match your file name. The grep statement will fail to show you the direct URL.

Let me know if you find any bugs in this script or if there is a better way to do it.
