I'll explain this with a real-world example. Let's say I've been downloading many images from the internet, with gibberish filenames like Dr1yGpDUUAAvBs6.jpg. How should I quickly rename these images?
From the Pictures menu, choose 'Resize images...'
Click 'Browse...', choose the directory containing the target images and click OK.
- From the Rename menu, click 'Add numbered prefix'.
This will add a prefix with a number like () to every filename. Why is this useful? It locks the order of images in place, such that I can now freely rename images without worrying about sort order. Without this, it would be cumbersome to rename every image in a directory because I would keep encountering images that I had already renamed.
- Press h to rename the current image.
(Conveniently, the numbered prefix isn't shown and I don't have to be concerned about it, I can type in any new name and don't need to include the prefix).
Press left/right arrow keys to browse images.
When each image has a reasonable name,
I can go to the Rename menu and click 'Remove numbered prefix'
We've now renamed the images.
