How to Resize Images in Photoshop at Once Automatically (Part 1 of 2)
The purpose of this How-To article is to describe in details the process of automating the batch-resizing of images using the Photoshop software. That is, if you have a large collection of raw images, especially if you are a photographer, you might find the need to re-size the images to decrease their dimension and file size.
For the smooth processing of the images, for the purpose of this demo, you need to do the preparatory steps below.

Preparing the photos for processing

Please remember that the process will automatically re-size all images in a certain folder and the "final size" or resulting size is fixed or constant. So it is very important to make sure that the required images are:
  1. stored in a single folder as the "source" of the entire process
  2. all pictures are in the same "orientation" - all portraits or landscapes; all tall or wide
  3. the images are just copies of the original photos to ensure that the originals are preserved

Here is my sample pictures for the purpose of this demo, the screen shot showing all my pictures of size 860x571.

Doing the Work in Photoshop

Now that the images are ready for processing, please do the following in your Photoshop:
  1. Open Photoshop
  2. Click on File menu => Scripts => Image Processor...

  3. The Image Processor dialog box will then open.
  4. Under Step 1, use the Browse button to select the source folder, this is the folder location of the images that you want to process.
  5. Under Step 2, select the option that says "Save in same location". NOTE: This will result in a "JPEG" folder being created in the source folder where all the processed images are stored.
  6. Under Step 3, select the File Type of the resulting images. In this demo, I chose "Save As JPEG". Then this is the most important part - select "Resize to Fit" option then enter the new dimension. In thid demo, my original image size is 860 x 571 and I will resize them to 800 x 531.
  7. The Image Processor dialog box should look similar to this:

  8. When everything is set, click on the RUN button and watch as Photoshop does the resizing of your images on the fly! This is in fact fun as you will see Photopshop opens the images individually and resizes them. The process can take longer depending on the number of images you are processing.
