Is there any way to improve the loading time of PrestaShop v 1.6 or to add lazy image load from the source? If that's is not possible what modules would you recommend to use to increase the loading time?
Anyway, if the problem is with images, you have to compress their. You can do it, in bulk mode, downloading all img folder with FTP, and, after, compress their with a program. I'm using JpegMini.
loading="lazy"
To all img tags:
<img src="[...]" loading="lazy" />
best answer.If you have some tech skills, you can easy add a lazy loading for images.
Now, html 5 implements lazy loading nativly. You should add:
HTML:loading="lazy" To all img tags: <img src="[...]" loading="lazy" />
I cant't tell you where go or what to edit, 'cause depends from the theme and plugins. Certanly, you have to edit some files in the theme.
Probably exists a module to do that, but i advise against you to install new modules.
