I really hate it when webmasters post images and photos on their websites that reveal next to nothing. This is especially frustrating on shopping sites when you want to take a closer look at an item that you consider purchasing. If you cannot make out the details, it is likely that you won’t buy the item. You sometimes can click on the image to be taken to a page with a larger version of it. Sometimes though, the image does not get larger at all, which is equally frustrating.

Probably the best option to resolve those issues are tools that let you zoom images directly on the website they are posted on. One of the most promising programs for that job is the Firefox add-on Image Resizer/Scaler.

Unlike other programs that display a larger version of the image on mouse over, it acts only when the user wants to resize an image.

All you need to do after installation is to hold down the left mouse button on the image that you want to zoom, and either move the mouse to the lower right corner to zoom in, or the upper left corner to zoom out.

The extension will automatically resize the image on the current page. Please note that the image quality may deteriorate if you increase the size of the image.

Depending on the page, you may be able to zoom the image on top of other page elements, or not. Some sites limit the image space which means that your image won’t show up in full if you make it larger on that page.

The Firefox add-on offers additional controls besides the left-click dragging to resize the image. You can automatically maximize an image with a double-click on it, and reset the image to its original size with a right-click.

Firefox users can download and install the Image Resizer/Scaler add-on from the official Mozilla Firefox add-ons repository.
