Hello need help with creating a macro to modify a batch of images by resampling not resizing

original size 480 x 320 px what I need is 480 x 480

100dpi is fine

by resampling the image become elongated and is exactly what require..I can do this manually but I have over 200 images that need to be resampled not resized resizin will only add, remove crop images without changing it aspect ratio

I thought the macro recor had start and stop buttons but can't find the recorder the only recorder is a side tab but no start record function

or if anyone has a macro to share that would do a RESAMPLE it would be appreciated

thanx in advance

 You can record a script by hitting CTRL F3. This will open the Recorder Docker. The Red button starts recording. If you can't see it, perhaps the Docker is collapsed. IN that case the little black arrow at the top will expand it.
