Resizing images is quick and easy in Photoshop Elements
Batch resizing photos in Photoshop or Windows Explorer
If you need to resize lots of images, it doesn't make sense to process them manually in Photoshop. You can use the ImageResizer utility - which we mentioned on the previous page - to scale down a selection of photos in Windows Explorer.
To select multiple photos, click the first one to highlight it, press Shift and then click on the last one - everything in between will be selected. If you want to select several photos which aren't next to each other in the list, hold Ctrl instead of Shift and click on each photo you want to resize. You can continue selecting photos with either Ctrl or Shift to add to your existing selection.
Finally, right click on one of the selected images and choose ImageResizer from the menu which appears. Set your options for resolution and where to save the new images, and you're done.
If there are certain photos which need rotating, you can choose Rotate Clockwise or Rotate Counterclockwise from the same right-click menu. Again, this works if you have several photos selected, but make sure they all need rotating the same way before you do it.
In Photoshop, you can also resize batches of photos. If you have the full version, you'll find the Image Processor under Scripts in the File menu. For Elements, it's Process Multiple Files in the File menu. With these tools you can resize files in a particular folder and save them as a different file type with a compression level of your choosing.
