@mitu Alright, thank you for your help.

You can connect a second display only over the GPIO - something similar to this setup should get your 2 independent displays - one for normal gaming via HDMI and a 2nd one over the connected over SPI (GPIO pins). The 2nd display can be used for showing the images (via fbi) or even videos (via omxplayer).

@noobsaibot It depends, you still haven't provided any info about your system.

Sorry for the late response. Yes I did try the option to stretch the image but that did not fix the problem.

thanks for the reply i will check it out. by doing what you said, will the slideshow option show in the ES UI menu like the other image .

Yes it is still available, just update Kodi first in RetroPie-Setup before downgrading.
