How Do I Set Picasa as My Default Photo Viewer?

By Nick Peers Updated February 9, 2017

Although Picasa 3.9 is not certified for operation on the Windows 8.1 operating system, you can install and use it without any problems. The default photo viewer in Windows 8 is the Modern UI Photos app, but you can configure your computer's operating system to use the Picasa Photo Viewer by changing the default programs settings. Finding the default programs settings is not difficult, but the procedure is different from Windows 7.

Click Browse and select the destination folder. Picasa 3.9 requires around 70MB of free disk space. Click Install to install the program on Windows 8.1. Usually, Picasa 3.9 is installed in less than a minute.

Step 4

Customize the settings and close the wizard.

Enable or disable the various options on the Completing the Picasa 3 Setup dialog by checking or unchecking their boxes. You don't need to run Picasa to set it as the default photo viewer, so you can safely uncheck the Run Picasa 3 box. Click Finish to close the setup wizard.

If you leave the Send anonymous usage stats to Google option enabled, Picasa sends usage statistics to Google for analysis.

Optionally, you can choose to open only specific file types with Picasa Photo Viewer by clicking the Choose default apps by file type link.

To change the default app for a file type, locate the file's extension, click the default app and select a different program from the list. For example, you can open JPEG files with Picasa Photo Viewer, but use the Photos app for GIF files.

Tip

If you uninstall Picasa, Windows uses the next available app to open images -- Windows Photo Viewer in most cases.

If you can't find Picasa Photo Viewer in the list of available apps, uninstall the program completely, restart your computer and then reinstall the software.

In Windows 7, change the default program by clicking the Start button, typing "Set default programs" and then clicking "Set Default Programs" to open the Control Panel. Select Picasa Photo Viewer from the list of programs and then click "Set this program as default."
