+### Previewing an image
+
+Since 0.43.0, fzf has experimental support for [Kitty graphics
+protocol](https://sw.kovidgoyal.net/kitty/graphics-protocol/), so if you use
+Kitty, you can make fzf display an image in the preview window.
+
+```sh
+fzf --preview='
+  if file --mime-type {} | grep -qF image/; then
+    kitty icat --clear --transfer-mode=memory --stdin=no --place=${FZF_PREVIEW_COLUMNS}x${FZF_PREVIEW_LINES}@0x0 {}
+  else
+    bat --color=always {}
+  fi
