Automatically swapping an image for another on the server

Hi guys,

I am new here, glad to have found this forum.
Just a quick question.
I am trying to figure out a way to automatically swap a file for another one on the same location on the server at a given time.
This image is the splash screen of my IOS app and the url is pointing to it.

Let’s say I have a new version of “picture1.jpg” that needs to take the place of the old “picture1.jpg” on Sunday at 12pm.

This picture will need to change up to 20 times a month and I want to automate the whole process.

Is that possible? How can this be achieved?
Thanks for the pointers.

Cron job can be used, not sure which language you use but you essentially want to run the cron on Sunday at 12pm that:

Removes the old image
Adds the new one from a holding folder on your server
