Resizing Images to work with Neighbourhood Alert

When creating an alert to send out publicly, images included within the body of the alert should be no more than 600px wide. The following guide will explain how to resize an image in both Microsoft Paint and Adobe Photoshop.

Please note, you can skip the resizing process by sending out alerts on Rapport. This is because Rapport will automatically resize any images automatically.

 


Microsoft Paint

Begin by right-clicking the image you wish to resize, and select “Open With > Paint”.

 

Once this has opened in Paint, locate the “Resize” button in Paint on the top toolbar and click this.

 

You are now given the option to resize the image by percentage or by pixels. For more precise measurements, select “Pixels”.

 

Now, we are able to resize by exact pixel length. In this example, we are going to resize an image with a width of 1240 pixels to 600 pixels. To do this, we change the pixel value in the box, as shown.

Note how the vertical value has also changed. This is because the “Maintain aspect ratio” box is ticked. It is best to keep this box ticked to keep the image to its correct aspect ratio. Then click “Ok”.

You should now see that the image has resized to the measurements shown (you can see the exact measurements of the file at the bottom of the open paint file, shown below).

 

Now this new image just needs to be saved. It is best to save it as a new file and not overwrite the original, as the original file size may be required in the future.

Clicking “save as > PNG picture” is preferred over a JPG picture, as PNG uses lossless compression (which helps provide a higher quality image).

When saving the newly formatted image, save the file with a slightly altered name. In this example the original file was called “Koala.png”, but now I have resized it to a width of 600px, I have saved this edited version as “Koala_600.png”. This prevents overwriting the original file.

Once done renaming the file, you can click save and you now have the image with your desired measurements.

 


Adobe Photoshop

 Before editing in Photoshop, please ensure you have Photoshop installed on your computer. Once Photoshop is installed, begin by right-clicking the image you wish to resize, and select the option “Open with > Adobe Photoshop”.

Once Photoshop has opened, navigate to “Image” on the top toolbar, hover over it, then select “Image Size…” from the drop-down menu. You can also get to it by using the keyboard shortcut “Alt+Ctrl+I”.

 

Once this has opened, begin by clicking the link icon (shown by the mouse in the image below) – This will maintain the image aspect ratio.

Once this icon has been clicked, you should see 2 lines appear which visualise the width and the height “linking together”.

 

Now you can set the width to the preferred pixels you would like (in this case, 600) and the height should automatically adjust. Then click “OK”.

Now the image is ready to export/save. Begin by hovering over “File” on the top toolbar, followed by hovering over “Export” on the drop-down menu. Then select “Quick Export as PNG”

 

When saving the newly formatted image, save the file with a slightly altered name. In this example the original file was called “Koala.png”, but now I have resized it to a width of 600px, I have saved this edited version as “Koala_600.png”. This prevents overwriting the original file.

Once done renaming the file, you can click save and you now have the image with your desired measurements.
