Sometimes in iPhoto you want to change the names of a whole bunch of photos. For example, you might want to number them sequentially, with a prefix indicating the name of the album they’re in. That’s a great idea: a name like “Texas Barbeque Contest-001” is a lot more descriptive than “IMG_001.jpg” but who wants to do the work of renaming more than a couple of photos by hand? No one, that’s who. That’s why iPhoto has a Batch Change feature.
Here’s an example.
A few weeks ago I had the bright idea of weighing myself more or less daily and using my iPhone to take a photo of the readout on the scale. Thanks to Photo Stream the pictures magically appear on my iMac, where I put them into an album. Here’s how it looked a few days ago. Yes those are my toes.
Nice collection of photos but the names are not helpful at all. I wondered whether I could rename them to reflect the date that the pictures were taken (and of course the photos know when they were taken because the iPhone stamps that information into every photo it takes). Turns out it was easy. First, I selected all of the photos in the album. Then I went to the Photos menu and chose “Batch Change…”, like so:
That led to a box, which I configured as shown below.
Then I clicked OK and that was it. Here’s the result. So much better!
