Full Screen Web Image Viewer is a browser plug-in to view in full-screen mode the images you find in the web sites you visit. This program integrates itself into either Internet Explorer or Mozilla Firefox, adding some options to the contextual menu that opens whenever you right-click on an image.
These options will allow you to view the image in full-screen mode, choosing among the Best Fit, the Cut Fit, or the Stretch Fit options.
Best Fit will show the image as big as it possibly can while preserving the aspect ratio. Cut Fit, however, will cut the image to make it fit the size of the screen without distorting it, while Stretch Fit will fill the screen with the image completely ignoring its original aspect ratio.
As most plug-ins, this tool comes with no interface, working directly from your browser. At the time of writing this review, Full Screen Web Image Viewer successfully integrated itself into Internet Explorer 8, but failed to do so with Mozilla Firefox 3.6. It did not even appear as an installed plug-in.
