Non-georeferenced photos to train algorithm

Thanks for your answer. I am a colleague of Manuel, the one that posed the question. Of course we will only upload pictures taken by our team. Maybe I should say we are an Spanish institution (CSIC) promoting the use of iNaturalist all over the Pyrenean range. We are profesional botanists, and we have made a full list of pyrenean plants (more than 4000; most probably not only are listed or observed yet in iNaturalist). In particular we expect a scarcity of pictures for Pyrenean endemic plants. For that reason, it could be very interesting to upload pictures of plants we already know their names, taken in the Pyrenees, even if they are not georeferenced. Do you think that would be possible and recomendable? Our intention is just to improve the matching of the algorithm for Pyrenean plants. Thank you very much
