I'm looking for image editing software that will allow me batch edit a group of images. For example, I want to select a group of images, and create thumbnails out of them without doing them one at a time. Any recommendations?

Almost any image editor allows batch operations, so if you already have a favorite editor, try reading its documentation.

Since you posted your question on this web, I will tell you more about two tools available here that can do batch image operations.

• Picture Resizer (freeware) can create thumbnails without problems and uses a drag and drop interface.
• RealWorld Photos (shareware) is a full photo editor and it can apply operations on image in batches. You can for example configure it to create thumbnails and also add a shadow to the images in one step.

You should try ReaConverter!

It looks like ReaConverter 6.0 public beta is freeware.

ReaConverter is a powerful batch image editing software.

Take a look:
