SOLVED Background Image not updating
HI i try to set an radar image dsiplayed as background image on my mirror.
At the moment i try with: MMM-BackgroundSlideshow which i found does displaying and scaling the image very well.
In the Background i have a cronjob which downloads and converts the radar image from another source.
My problem is that the browser newer updates the image due to caching.
Even if i see in firefox debugger that the image got downloaded with 200 the broser does not update the image, als just reloading the page is not enough i have to “shift” reload the page to update the image.
Is there a way i can invalidate the cache?
Tried also adding a timestamp to the image and deleting the old one. But MMM-BackgroundSlideshow does no reread the folder content while running. And is i get a new image every 10 minutes i don’t want to restart the whole application.
i would change modules… MMM-ImagesPhotos reloads the folder on a configurable cycle.
@roadfox huh? it puts the images in the background too.
i gave it a try. MMM-ImagesPhotos is adding the image as an overlay with opacy, but i cannot figure out how to set the opacy so that the other values shine 100% trough.
oh i feel so stupid, i startet with fiddling in css and z-index and did not see that i can just set:
i’m very happy now, after adding a timestamp to the downloaded filename the image is updating now nicely
