desktop image rotator


My favorite desktop image switching utility chbg seems to have problems in Debian Lenny, so looking for a replacement.

The requirements are simple:
-rotate through images in a specified folder or list (either is ok)
-configurable image change interval
-continue from previous image on startup (or next image)
-with a gui or not, does not matter (but simple is better)

Tried to look for one with these requirements, found none..
Any ideas?

Check out the program called "feh"
You should be able to get it with apt

Thanks for the tip Zaskar
I played with feh for a while and it is a nice tool, but I still couldn't get the looping quite the way I want it.

So I thougt I'll use "hsetroot" and try to script the rest.. The result appears to work, but my bash scripting skill are very rudimentary, so I attached the "proto" below for anyone with better experience to comment.

Usage for setup: --setup <image folder path>
Usage for execute: <image switching delay in seconds>

Code:
#!/bin/bash

# If setup was requested, just build the image list and exit
if [ "$1" == "--setup" ]; then
   find "$2" | grep -i .jpg > .background_list
   exit
fi

# Make sure the image switching delay is not unreasonably small
delay=$1
if [ "1" -gt "$delay" ]; then
   delay=1
fi

# Get the number of images in the image list
img_no_max=`awk 'END {print NR}' .background_list`

# Set the next root window image, delay for a while, repeat..
while [ 1 ]; do
   # Get the order number of the next image in the image list
   img_no=`cat .background_no`
   # Get the image name, according to the order number
   img_name=`awk -v no=$img_no 'NR==no {print}' .background_list`
   # Display the image
   hsetroot -center $img_name

   # Increase the order number for the next image.
   # Reset the count if last image has been displayed
   img_no=$[$img_no+1]
   if [ "$img_no" -gt "$img_no_max" ]; then
      img_no=1
   fi
   echo > .background_no $img_no

   sleep $delay
done
