How to automatically rename images at a specific time?
I have two files: wp-content/uploads/banner.jpg and wp-admin/uploads/banner-off.jpg
Using only HTML I display one image outside of my website.
<img src=".../wp-content/uploads/banner.jpg">
How to everyday at 16:00 change banner.jpg to banner-off.jpg and banner-off.jpg to banner.jpg?
Outside my website I can’t use anything instead HTML tag.
