Pictures
Aligning image resolutions is necessary because different screens have different pixel densities
and could display images of the same resolution differently.
To increase the resolution of an image, multiply the number of pixels in each image by a specific scaling factor.
Icons
An effective icon is an element that helps users understand the meaning of information at a glance.
To enhance the quality of displayed images, use only icons in the SVG format.
Always test images on real devices.
An image that looks great during the design process may become pixelated, stretched,
or shrunk when viewed on different devices.
