feh on linux keeps looping despite of --cycle-once [SOLVED]

SOLVED

I am using a le potato running raspbian, to display pictures on a screen. These pictures are in a shared folder I can access from my windows pc. The input is where the pictures go, and output is scaled so they are actually fullscreen. I have some code to check if any changes are made in the input folder, so it will adjust the output folder.

My problem: I need the slideshow to loop once, then close, revealing google chrome underneath. Wait for a set amount of time (10 minutes) and then play the slideshow again.

For some reason, the slideshow keeps playing even though I use --cycle-once. I have tried to use a loop count, but this did not do anything. T tried to have the code delete the pictures in output after vieuwing them, and then after output is empty sleep and restart, but it didn't see when a picture was viewed.

Sadly im pretty new to linux and coding, and have used chatGPT for most of my work. I have been bashing my head against this for 3 days now, and hope someone can help me.

Current code:

PHP Code:#!/usr/bin/bash

input_folder="/home/pi/Public/screen/input/"
output_folder="/home/pi/Public/screen/output/"
slideshow_pid=""

###Functiontoupscaleandcopyimagesfromtheinputfoldertotheoutputfolder
upscale_and_copy(){
localfile_path="$1"
localfile_name=$(basename"$file_path")
localoutput_path="$output_folder/$file_name"

convert"$file_path"-resize1920x1080^"$output_path"
}

I have tested the following, When I run JUST the following code, it STILL keeps looping endlessly, so it's feh itself that's causing the problem somehow. If anyone knows what the problem might be, please tell me.
