To use Fookes Easy Thumbnails you should open the Windows software and click on "Thumbnails" or more commonly referred to as " Images". You will then see a list of thumbnails which have been created by the software. Clicking on any one of them will give you a full screen view of the generated thumbnail. Select the one you want and click "Save to Image" to save the image to your computer
I am a big fan of Fookes Easy Thumbnails as it does an excellent job of optimizing the quality of the image even if it is a small jpeg file. Many free tools do an excellent job of optimizing the quality of the image but they usually over optimize the image and as a result the image starts to look flat. With Fookes Easy Thumbs you don't have to worry about this because the program uses the latest algorithms to get the best quality images. There are a couple of other minor issues with this software, for example, it lacks the ability to compress JPEGs, but overall Fookes Easy Thumbs is a great program to download and use. To conclude my verdict, if you are looking for a good way to create simple, high quality, and easily embeddable thumbnails then download Fookes Easy Thumbnails and give it a go.
