XF 2.1 Change banner image based on day number?

[Mave]

I've prepared 365 banners like so:

bannerimage_1.jpg
bannerimage_2.jpg
bannerimage_3.jpg
...
bannerimage_365.jpg
bannerimage_366.jpg

How can I automatically let the header image (banner) change based on the day number?

Thanks in advance!

bannerimage_{{ date($xf.time, 'z') + 1 }}.jpg

 

[Mave]

bannerimage_{{ date($xf.time, 'z') + 1 }}.jpg

Thank you @DL6 this works but only if I re-save the file containing the css rule every day, not automatically for some reason.
Any idea why this might be happening?

Anyone has any idea?

bannerimage_{{ date($xf.time, 'z') + 1 }}.jpg

works, but does not change unless I manually re-save the file every day.

Anyone? Is this a cache issue? (though I'm not running any addons that affect this)

Try putting your CSS in the PAGE_CONTAINER template

<style>
css here
</style>

or

<xf:css>
css here
</xf:css>
