How would you cut an image, equally, in thirds?

[JugglingZero]

I highlight the layer (cmd click) and then hit C. I have the crop tool set to "Rule of Thirds" so I can quickly see the image in equal three parts.

I cut the upper third.

Then I have an image I cut in half.

Three equal part.

Do you have an easier way you'd suggest?

With my current project this is an action I must repeat.

The only catch is ... the images are all unique.

Specifically they are old newspapers.

Instead of one looooooong column - I split it into three columns across a white background. Line them up. Make then more readable.

Anyway.

How would you cut a long, thin, newspaper column into thirds the fastest?

I have done this many times. My standard method is to open the image, select and ⌘C ⅓ of the text with a rectangle - just eyeballing the three parts. Then I open a new tab with the contents of the clipboard and ⌘V then go back to the original tab and select the second column of text go back to the 2nd tab and paste - you will have to correct cropping for two more columns. Then repeat that for the third column. This has the advantage of keeping the original image intact - to make changes as needed - and have your three column image - after you save it.
