Hi barushahmedov,
Thanks for reaching to us.
Glad to hear your issue has been resolved.
Yes, viewing images in full-size may caused the speed of loading, but our theme is optimized for speed and should not significantly slow down your website. However, it’s possible that your website’s performance is affected by the content you have added. For instance, the use of too many plugins, large unoptimized images, or other resources can slow down your website.
We recommend that you remove any unnecessary plugins and install a JS & CSS optimization plugin such as WP Rocket. Our guide on how to optimize your website using our themes can be found here: https://xtemos.com/wordpress-performance-optimization-the-ultimate-guide-in-2021/.
If you have any further questions, please don’t hesitate to reach out.
Regards,
