Screen Savers in Photoshop Elements
If you have two or more photos you want to use, you can create a screen saver in Windows or OS X. Follow these steps in Windows 7:
Select the desired photos from the Organizer.
Choose File→Export as New File(s). In the Export New Files dialog box that appears, choose JPEG as the file type.
Select your photo size and choose a quality setting.
Use a size that matches the resolution setting you’re using for your monitor. Use a quality setting of 12 for maximum quality.
Click the Browse button.
Click the Make New Folder button, save the photos as JPEGs to that folder, and name the folder something appropriate, such as Screen Saver. Click OK.
Choose whether to use the original names of your files or a common base name, such as screen 1, screen 2, and so on.
If all goes well, Elements informs you that it has executed the command.
Right-click your desktop and choose Personalize. Then select Screen Saver from the window's bottom-right corner.
Click the downward-pointing arrow in the Screen Saver box and select a screen saver.
Specify your other options, such as wait time, power settings, and so on.
Click OK to close the window.
Mac users can create custom screen savers even more easily:
Choose System Preferences from the Apple menu.
Click Desktop & Screen Saver and then click the Screen Saver tab.
To choose one of your photos, click the plus sign and choose Add Folder of Pictures. Find the folder with your images and choose the photo.
Click Test to see a preview. If you’re happy, click the Close button in the top-left corner.
