I'm looking for some help in writing a batch script to resize a bunch of .jpg images.
I don't have much experience with batch scripts. But this task will be preformed on a windows machine & so I thought a batch script might be a good way to go.
I'm always interested in hearing alternative ideas & approaches, or being made aware of elements I haven't thought of.
Below I have listed the basic steps/needs of the script:
1) The images are located in a folder & are all(or should be) 500 x 500. 2) I need copy & past the images to a new folder, where they will be resized to 250 x 250. 3) I then need to repeat step 2 but this time resize to 125 x 125.

Click the first photo, then hold down your ”CTRL” key and continue single-clicking on each photo you wish to resize. Once you have chosen them all within a specific folder, let go of the CTRL button and right-click on any of the photos and choose ”Copy”.
Resize multiple images by batch processing them Now you can batch process your images to resize them all. To do this, open Photoshop, then go to File > Automate > Batch. You should now see the Batch window. Choose the set that you created your action in, and then choose your action.
You can resize multiple images in Python with the awesome PIL library and a small help of the os (operating system) library. By using os. listdir() function you can read all the file names in a directory. After that, all you have to do is to create a for loop to open, resize and save each image in the directory.
Once you install ImageMagick for Windows, you can use magick command-line tool, e.g.
magick.exe mogrify -resize 250x250 -path 250x250/ *.png *.jpg magick.exe mogrify -resize 125x125 -path 125x125/ *.png *.jpg Note: Make sure your magick.exe command is in your PATH system variable and you're pointing to the existing or created the destined folders (e.g. mkdir 250x250/ 125x125/ in above case).
