Hi @creativa1976
If you meant replacing the slider below your header, then you should find the place where that slider is coming from.
The container element of your current slider has this ID: home-slider so you could search for this in the files of your theme, like you see here:
https://smartslider.helpscoutdocs.com/article/1935-troubleshooting-with-your-browser#findcode
It should be in a context something like this:
<section id="home-slider" ...>...</section>
Once you managed to find it, you should create a backup of the file ( just in case ) then you could publish your slider into this container with PHP code as you see here:
https://smartslider.helpscoutdocs.com/article/1720-publishing-on-wordpress#php
and then delete the unnecessary codes of your old slider.
After that you should upload the modified file back to your server and you should see the changes.
If you can not see any changes then you will most likely have some kind of cache that needs to be cleared. For example if I check your site now, then I can see that the HTML is minified and it seems the page was optimized by KingComposer Page Builder.
Best regards,
Laszlo.
