Deferred images library for Contao 4

Now compatible with Contao 4.6 !!

About

Contao normally generates (resizes) the images on a page during page generation. This can lead to long page load times or, in the worst case, script timeouts due to server restrictions.

This library shifts the image calculation from page generation to the time when the image is loaded in the browser. As a result, pages will have very short loading times and script timeouts are avoided, even with hundreds of images on a page.
