thank you for heelp

I think you need to provide more info. For example:

  • what device are you talking about, and what SD card? Do you mean you want to install OpenWrt on a Raspberry Pi or similar and put such media files on the same card? * How do you want displaying the image file to be triggered or initiated? By which device?
