When using the app on my phone, I know how to group several photos into one ‘observation’. When I am using the browser on my computer to create an observation, I have not been able to figure out how to upload multiple photos for one observation. I always end up with multiple observations, each having one photo. (using a mac, uploading from google photos)
Welcome to the forum! You should be able drag and drop photos onto each other. I think you can also select multiple ones and select the combine button.
I have never been able to do this on my phone, only on my laptop. The only way to do it on my phone is to upload only one species at a time, “select all,” and “combine.” If I try to do it any other way, the screen freezes in such a way that I can’t scroll to the upload button.
