I used to use a third party application to batch resize images as a certain size is required to display properly on my personal blog. Anyhow I use Adobe Photoshop to manipulate images in many other ways and wanted to see if it would do the same batch resizing which would require one less application to be installed. Sure enough Photoshop does a great job of batch resizing images to any set sizes you prefer.
**NOTE** After writing this article I discovered a different way to resize images that is actually much easier. I wrote a new article located here describing the method which utilizes the Photoshop Image Processor.
In the example scenario below I resize images based on height and width maximum size settings. The width cannot be larger than 640 pixels and the height cannot be greater than 480 pixels. Follow the instructions below to set up a batch resize action followed by automating the batch resize of numerous images at the same time.
