By setting specific dimensions for the images, you can ensure that they are displayed uniformly throughout your design. This not only creates a cohesive look but also makes the overall presentation more professional. It is important to consider the aspect ratio of the images when determining their size. This will help you avoid distortion or stretching of the images when they are resized to fit within the layout. By setting specific dimensions, you can easily adjust the images to make sure they fit properly without compromising their quality or resolution. By taking the time to set specific dimensions and adjust the images accordingly, you can create a polished and professional look that will leave a lasting impression on your audience.
