The images are CC0 from Pixabay, the text is created by me, also CC0. I can clarify that on the signature, but as you know, in CC0, attribution is not necessary. Would you recommend adding "All images in the post were taken from Pixabay" to my signature just for the reader's comfort? It would be a bit redundant as the intention is for neither author to claim possession of anything, but it would be clearer.
