What are images? (also known as pictures)


An image (from Latin: imago) is an object that depicts visual perception, such as:

  • a photograph
  • or other two-dimensional pictures,

Example of images and their dimensions

Name Dimension
Album Cover 1400 × 1400 px
Animated Logo 500 × 500 px
Animated Social Media 1080 × 1080 px

There are two ways (types) of representing an image:

Type Description
Raster graphics (also called bitmap) dot matrix data structure. The image is defined in terms of rows and columns of individual pixels, each with its own color.
Vector graphics geometrical primitives such as points, lines, curves. For instance, a single straight line is described in terms of its two endpoints.


They mostly propose free and paid images.

The difference in these types of graphic images becomes readily apparent when a drawing is enlarged.

Most output devices display graphics as a raster or bitmap image. The real difference between drawing with bitmap graphics and vector graphics is the point at which the image is converted into a bitmap.

In the case of vector graphics, this conversion is done at the very last step before display, ensuring that the final image matches exactly the resolution of the output device.
