Firefox and Thunderbird are famous browsers that also come with the feature of zoom that can zoom the entire page for you.
But what if you want to zoom in or zoom out only the images present on the site and not the whole web page? This feature is added by the plug-in called Image Zoom.
Easily zoom in, zoom out, fit image to screen or set custom zoom on individual images within a web page. This added functionality is achieved by the using the combination of mouse clicks and scroll wheel.
You can zoom all images on a web page with a single command or make all images on a page zoom with the browsers text zoom feature.
