How-To: Batch Resize Images Using PhotoShop
1. Open up Adobe Photoshop
2. Go to File > Automate > Web Photo Gallery...
3. The Web Photo Gallery window should pop up. Don’t Panic!
4. Under Source Images, click the Browse… button, then select the folder that contains all of the images that you want resized.
5. Repeat the process for the Destination… button. You may want to Make New Folder – this is where your new resized documents will appear, along with some html that will allow you to browse the folder. To avoid infinite loops, the only thing that is important here is that the destination folder should NOT be the same as the source folder, or a subfolder thereof.
6. On the Options: dropdown you’ll see Banner; not strictly necessary, feel free to customize the “Site Name”, “Photographer”, etc. – this information will land in the html file that is output along with the resized images for browsing purposes.
7. For resizing purposes, select the Options: dropdown Large Images – this is where the action is. There are several steps here:
a) Make sure that Resize Images: is checked;
b) The default size of the resized images is set to 350 pixels – increase or decrease this number as appropriate
c) By changing the value of Constrain:, you can control how you want the image to be proportioned upon resizing; selecting Both will make the image resize into a square of width and height the number you chose earlier.
d) Set a value for JPEG Quality: to a value that you’re comfortable with - the higher the value the better the quality, BUT the larger the file size
e) leave the Border Size: set to 0 – that is, no border.
6. Click the OK button on the upper right hand side of the Web Photo Gallery window, and Photoshop will begin the process. You will see images opening and closing as PhotoShop processes the resize batch.
You can write an action / marco to automate the above if you have the patience :)
