2nd featured image?

There’s two ways of doing this. Both of them require some programming work.

The first is to use the standard ordering in the gallery area for your posts/pages. Set it up so that all of the images are ordered and set 1 as your featured image. That way you can get the images in your template code and retrieve the second image to be used for a second feature.

The second way is to set up an additional meta-box area for your pages/posts that has a list of some sort with the available images in it. That will let you select which image that you want to display and save that as a custom vale for that post. Then in your template you can get the custom values, find if there is a secondary featured image and display it if there is.

the first way seems like it shouldn’t take too long.
But Im really lost on the second method and since I really want to learn wordpress, can you explain it a little more?

If you want to learn about custom meta-boxes, there are four great tutorials here: https://wp.tutsplus.com/tutorials/reusable-custom-meta-boxes-part-1-intro-and-basic-fields/

thanks…
That tutorial is a little over my head, i followed
https://wp.smashingmagazine.com/2011/10/04/create-custom-post-meta-boxes-wordpress/
instead and created

to create the sidebar image meta box, Id really want to change the html inside of it so that it functions just like the featured image one and allows you to set an image in the sidebar, Is there a way to do that?
