My MacOS X

A Quick way to resize images in batches could be  find that Preview has that functionality. Open the whole batch of images in Preview; the images will all open in the same window with thumbnails visible in the sidebar.

Select all of the thumbnails in the sidebar (with Command-A, or click the first and then click the last while holding Shift). Next, from the Tools menu, choose Adjust Size. You’ll be presented with a dialog containing options to resize to all the common 4:3 and 16:9 screen sizes, as well as the option to define custom dimensions. Images are scaled proportionately and resampled by default.

Save the resized images, and you’re done!
Preview will prompt you to save any changes if you attempt to close the window.

You can also use sips on the command line:
sips -Z 1024 *.jpg
will resample to a max of 1024 px for the long edge.
Note that sips rewrites images in place, so you should do this on a copy if you care.

I’ve been going through my iPhoto library trying to tag all the faces, which can be a time consuming task when you have a large library. But I found one small shortcut to help get rid of faces that keep popping up for people you don’t know.

When browsing a specific person in Faces, at the bottom of the window it makes suggestions of other faces that may be the same person. After clicking the Confirm Name button,  you’ll be able to:

• confirm (click or drag-select)
• deny (Option-click or Option-drag-select)
• name (Control-click to see the pop-up menu)

the face, you can also remove it.

Instead of clicking Confirm Name,

• select the image thumbnail with the unwanted face
• press the Space Bar to view the full image
• click the Name button that appears in the button bar at the bottom.

You can then remove the unwanted face, and when you click Done, you’ll be taken back to the Faces view.
