HTTPS for slider images

If you will note on my website, if you view the source, the slider image is getting called with http, and not https, causing Chrome to alert the visitor to a potential security issue…

The link it is pulling the image from is https://qscomputerservice.com/wp-content/uploads/2019/06/slider1.jpe.

How do I get it to pull it from https. Other images on the site are fine. All other pages show as secure in Chrome.

Thanks.
