+# This is a simple script that allows you to have image preview
+# in fzf, using ueberzugpp with fifo. For this script to work
+# you must add it to path, because it requires to call itself
+# during the preview process in fzf (line 42 -> $0).
+# Example usage:
+# ls | fzf-fifo
+# find $HOME/pix/ -type f -iname "*.jpg" | fzf-fifo
