Wow! Thank you very much for all the suggestions, they are extremely helpful.
I didn’t think that exporting would be so challenging.
Many of the photos relating to the observations only exist on Observation.org, so I’ll try playing around with the Excel/CSV import a bit.
Thanks @bazwal for pointing out that I am free to decide how and where I share my data. I hadn’t thought about it that way before.
Big thanks @streepvaren for the detailed instructions that is super helpful!
