Image in the slider

in each post, i select my image

What do you mean by selected? Only images that are set as Featured Images will show on the slider. https://ronangelo.com/add-a-featured-image-on-a-wordpress-post/

Also, there is no required width or height. The best size fit for your featured image depends on the width of the content area you choose.

do you have an example with the slider go well?

thank you, it is ok now with the featured images.
I didn’nt learn on the description

how is it possible to insert link to a page in the slider and not link to a post?

Hello,
Thanks in advance for you support. I’m currently using this Frontier Theme Version: 1.2.0. However, I’m having some issues as well with the slider. 1- I would like to add different images to show in the slider(no only one) Is that possible to place more than one image to show in the slider? If so, could you please tell me the steps to follow in order to make it possible? 2- I also would like the slider to show only in the home page of my site. However, currently the slider is showing in my home page and in my blog page. Could you please tell me how I can set the slider to show only on the home page?
3- The slider is fixed. How I can make the slider to move automatically? Please note: I’m not trying to make posts on the slider or neither to share any other information rather than a few pictures(images) about my site. That’s pretty much it! Thanks. Your response will be greatly appreciated. Please also include the steps to follow in order to fix the above issues. God bless!
