Photoshop’s Fit Image command is a great little tool I discovered today. It’s used when creating actions to be used later in the Automate -> Batch option.
When you are recording your Action, go to the File menu and choose Automate/Fit Image instead of opting to use the usual Image Size command.
If you want each image to be no bigger than 500 pixels on the long end, for example, type “500” into the width field and “500” into the height field. This will ensure that each image you process is no larger than 500 pixels wide or high, regardless of whether it is a vertical or horizontal image.
I use the automate option when creating thumbnails for my site, so this will save even more time now that I don’t have to open the vertical and horizontal photos separately and use different actions on them.
Holy crappers I’ve been trying to figure out how to do this in batch mode for months. Sweet!
