Take the Ghacks logo for instance. You will notice that resizing the window in Firefox after loading the image will reduce the size of the image automatically; Firefox resizes the image dynamically.

If the browser window is large enough the image is shown in its original size.

If the browser window is resized, the image is resized dynamically as well.

Firefox has a configuration setting for that. To make the change enter about:config in the Firefox address bar. First time users need to click the I’ll be careful button.

Enter the parameter browser.enable_automatic_image_resizing in the filter list and double-click it to change the value from true to false. Firefox will dynamically resize images if the value is set to true. A value of false will show the images always in their original size regardless of the browser window size.

The change is enabled immediately. Open tabs need to be reloaded once for the change to become active though.

Why would someone want to make the change? It makes sense for very large images, that exceed the screen resolution. Users who want to view those images in their original size need to download them to the computer to do so, as Firefox resizes the images automatically. Making the preference change allows those users to view the images directly in the web browser.

Multiple Image Resizer [homepage] is a software for Windows that requires the .net Framework from Microsoft. It – as the name suggests – offers functions to resize, and edit, multiple images at once. To make things as easy as possible it offers functions to scan for images, add folders and the images within or add individual images that should be processed.

Images can be previewed if the user selects them. Several processing options besides resizing the images can be selected. Those are the options crop, rotate and flip, border, add text and overlay image. By default only the resizing option is selected.

Each option has its own configuration menu. The resizing menu for instance offers several ways to resize the images. The user can select a certain width and height in pixels, a percentage value, a dimension and several other options.

A text can be added to the image. This can be used to sort of watermark images or put a small copyright notice in a corner of the image. The font and its color as well as the position of the text can be selected.

The processed images can be saved in various different formats including the most used ones like jpg and png.

The tool itself is very easy to use with only a few options to choose from. If there is something that I would have to criticize it would be that the program window cannot be resized. Only a small portion of large pictures is shown and you have to use scrollbars to look at other parts of the image.

Resizor needs some tweaking to become a real great software but what I have seen so far is impressive enough already. It shines when resizing images with wide panoramas. It lead to some distorted images however. I tried it on an image of a person sitting in a chair with only a few pixels on the left and right and it resampled the image so that the persons head would be really big while the rest of the body much smaller in comparison.

There should be a way to define areas of importance which would really mean that distortions like this would not happen anymore.

Text on the other hand can be resized quite easily to adapt to certain resolutions. Resizing images can also be problematic because they can easily look distorted or out of proportions when you do so. This new technique uses a system to determine the importance of pixels in an image and remove or resize the least important ones first.

This makes it possible to manipulate images without losing image quality or sharpness at all. Some tools can be used to mark spots on the image as important – faces for instance – or unimportant to further increase the quality of the resized image. Take a look at the demonstration video to get a closer look at this incredible technique.
