i modified something that i previously made (see https://forum.inaturalist.org/t/tool-for-making-observations-printer-friendly/4513/18) so that it can display photo URLs associated with each observation. here’s an example of how you might use it to view your observations: https://jumear.github.io/stirfry/iNatAPIv1_observations.html?user_id=dmitryshtol&per_page=200&locale=ru.
i didn’t add functionality to easily export results into CSV, but you can look at the thing mentioned here (https://forum.inaturalist.org/t/is-there-a-tool-code-snippet-that-allows-downloading-of-taxonomy-data-from-the-site/14268/6) to see how it accomplishes its export, if you wanted to do some coding on your own.
