You set a guide by clicking and dragging from a ruler into the canvas.

You can move it using the move tool. Moving back to the ruler removes it.



For lots of guides use use;  Image -> Guides -> Remove all Guides

The Gimp docs are your friend. https://docs.gimp.org/2.10/en/gimp-conce...uides.html

Edit: Just a reminder, Guides are saved with a Gimp .xcf format image. Only an internal setting. Exporting to some other format and not there.

Thank you very much, it solved !
