So I'm trying to make an "Image of the Day" template, but I'm having trouble with the image changing automatically each day.
I created a page (for example, Screenshot) with a subpage for every day (for example, Screenshot/October 6, Screenshot/October 7, Screenshot/October 8). On each of these subpages I display one image. The template transcludes a subpage depending on the day. Here is essentially the code:
{{#ifexist: Screenshot/{{#time: F j}} | {{: Screenshot /{{#time: F j}}}} | {{: Screenshot /default}} }}
This works well sometimes. Some days the image that the template displays changes on its own when the date changes. Other days I have to manually click "edit" and then "Save page" in order to refresh the image.
I essentially have two questions:
1. Why does this template work inconsistently; i.e., some days images changes on its own, and some days not?
2. How can I make the image always change on its own?
