To rename your photos, follow these steps:
- Select the photos you'd like to rename.
- Click the File menu, then choose Rename. You can also use keyboard shortcut F2.
- Enter a new name for these files. You have the option to include the date or image resolution in the filename.
- Click Rename.
Tip: Before renaming your photos, verify you've selected only the photos you wish to rename in your photo tray at the bottom of your Picasa window. After pressing F2 to rename your photos, confirm the number of files selected for rename is correct.
As you may know, files in the same folder on your computer can't share the same name. If you're renaming multiple files at once, Picasa will automatically add sequential numbers to your new filenames. For example,
photo-003.jpg, and so on.
