Configure KDE4's Device Notifier to Download Photos With Picasa

My wife has been asking me for some time to make it easy for her to dump photos off of our digital camera and upload them to Shutterfly. After some research, I determined that Google's Picasa software was capable of interfacing with Shutterfly, so I installed the Linux version in her Kubuntu laptop. However, when I inserted the memory card from the camera into the reader, KDE's device notifier pop-up only offered three options to process it: download the photos with Digikam, open the file manager or do nothing. I wanted a fourth option to download the photos with Picasa, and here's how I managed to get it working.

First, I created a new directory in my ~/.kde tree.

mkdir -p ~/.kde/share/apps/solid/actions

Next, I created a new file called picasa.desktop in that directory, and populated it with the following content:

[Desktop Entry]
X-KDE-Solid-Predicate=[ [ StorageVolume.ignored == false AND StorageVolume.usage == 'FileSystem' ] OR Camera.supportedDrivers == 'gphoto' ]
Type=Service
Actions=open;
 
[Desktop Action open]
# %f gives StorageAccess.filePath, %d gives Block.device, %i gives UDI
Exec=/usr/bin/picasa
Icon=/usr/share/icons/oxygen/32x32/apps/picasa.png
Name=Download Photos with Picasa

Picasa does not seem to come with a decent icon to use in the device notifier popup, so I did a bit of searching on the web and settled on the 32x32 icon at http://www.iconspedia.com/icon/picasa-2711.html. I downloaded this icon and stored it in /usr/share/icons/oxygen/32x32/apps/picasa.png.

Once everything was in place, I logged out and back in to get KDE to reload its configuration. Then I plugged the memory card into the reader, waited for the device notifier to pop up, clicked the device name and was greeted with a dialog showing "Download Photos with Picasa" as the first option for handling the device! Whoohoo!
