I couldn’t find any study proving that showing something like a blurry thumbnail before the image loads improves a user’s perception. Then I thought of progressive JPEGs.
Back To Basis: Progressive JPEGs

Progressive JPEGs have been proposed as a good practice for images, especially for sites used in slow networks.
