ImageLobe allows you to very easily apply complex effects to your image files. Simply drag an image onto the ImageLobe window and select the effect you wish to apply. Over 40 image effect types are available, many of them highly configurable. Then drag the image back out to save it. It's as simple as that. Try it out. All the features of ImageLobe can be tried in demo mode. Purchasing a license for $20 will allow you to use the application with large image files.
