How to Rename Photo File Numbers
If you have a collection of digital photos, it's possible that they were automatically given file names with consecutive numbers by the camera, such as "photo-001.jpg," "photo-002.jpg" and so on. After reviewing them on your computer and deciding to delete some, there will be gaps in the numbering sequence, going from photo 3 to photo 7, for example. You can quickly rename the photo file numbers into a new sequence with software that comes installed on your computer. At the same time, you can give a set of photos the same base name to indicate details to help you organize them, such as what day they were shot or the location.
Click "Start" from the taskbar and click "My Pictures."
Open the folder of photos that you want to renumber.
Click "Edit," then click "Select All."
Right-click on the first photo file, then click "Rename." This highlights the photo file's name so you can edit it. If this is a set of pictures you shot at the zoo, you could name this image "Zoo.jpg"
Press "Enter" on your keyboard to rename each photo with the new base name and to add sequential numbers to them, such as "Zoo-001.jpg," "Zoo-002.jpg" and so on.
Click on the "iPhoto" icon in the dock to start the program.
Click on the "Plus" button to create a new photo album.
Drag the photo files you want to rename from their folder on your hard drive into the new photo album. Right-click on the first image, then select "Batch Change."
Click on the "Set" pull-down menu and change it to "Title," then click on the second pull-down menu and change it to "Text." A text field will appear that you can type in a base name for all the photos, such as "Zoo" for pictures taken at the zoo. Click on the check box that reads "Append a number to each photo."
Click "OK" and iPhoto will rename each photo with the new base name and add sequential numbers to them.
