The purpose of using images in slides is to visualize the messages they accompany, thus reinforcing their meaning.

Just as a text written in small font cannot be read correctly, the visual message of small images is not conveyed properly because the audience cannot perceive all their details and features.

For this reason, it is very important to use large-format pictures that allow the audience to visualize all their features: luminosity, contrast, hue, brightness, shadows, etc., thus transmitting the message clearly.

The size of the images, as well as their quality, suitability and originality are important to catch the attention!
