How ImageFit works
You only have to install the add-on in Firefox, reboot the browser and you'll be able to check its effects. When you open a large image, ImageFit will automatically show it in the size that fits the window you have open. And if you change the size of the window, the image will also change.
The only configuration possible for ImageFit is that it can show information about the photo's original size, when we leave the mouse on the image for a few seconds.
Try out ImageFit free for Firefox and you'll be able to view images in the most comfortable and practical manner.
