Locate the template in the Editor where you wish to put the image. It shows the pixels needed for the image.
Note: The width is fixed while the height is variable.
In Microsoft Paint, we can make changes to the image. To begin, locate the image you want to alter on your computer and open it in “Paint".
Now, in "Paint," click "Resize" and then "Pixels." Then, alter the number to the image's width. It is 600 px in this case. The height will thereafter be altered automatically as long as the aspect ratio is maintained.
