How to take images from Flickr or Picasa as your screensaver

Your screensaver can display a variety of images, but if you want to personalise  it a bit, you can use your Flickr or Picasa  albums as a screensaver. Flickr offers an RSS feed with photos, but to integrate it with
Windows, you need a suitable screensaver  that uses data from an RSS feed. For this, you can use Google Photos Screensaver,  which you can download with Picasa.

CAUTION: While installing Picasa, remember to deactivate all unnecessary settings or the viewer if you do not want  to use it. After the installation, navigate to “C:windowssystem32” and look for the
fi le “gphotos.scr”. Create a backup copy  of this fi le in another location. If you do not want to use Picasa, you can uninstall  the program. Once you’re done, copy the backup fi le “gphotos.scr” to the system folder once more.  To set up the screensaver, click on “Appearance and Personalization” in the control panel and then on “Change screensaver” in the “Personalization” section.
Now, select “Google screensaver” from the drop-down box and click on “Settings”. Here, click on the “Configure” button to activate sources for the screensaver, including “Picasa”, “Photos from specific folders on my computer”,  or “Photos from public websites”. You can specify the sources for each option
with the “Configure” button. To set your  Flickr images, click on “Photos from public websites” and then on “Configure”. Now  enter the URL for the Flickr feed in the “Other photo feed sources” box and click
on “Add”.  After a short test, the entry will appear in the list and inform you of whether it
can access Flickr. You can add and activate  several feeds to add different sources. Confirm the changes with “OK”. Lastly, set  the visual effects, the time each image should be displayed for and choose to
display captions. Close the dialogue by  clicking on the “OK” button.
NOTE: The feeds load only 20 images
and stores them temporarily on your  machine. To get new images again, you must empty the Cache folder in your  user profi le regularly. To do this, open the user profi le in Windows Explorer and navigate to the folder “AppDataLocal  GoogleGBScreensaverimgcache”. Delete the existing JPG fi les so that new ones are
automatically loaded.
