I've already collected my attachments. I'm having an issue adding the images to the configurable pop up in AGOL. I've created a roundabout way of doing this but with 300 points and 400 images it would be nice to automatically do this! My roundabout way is as follows:
As the owner of a feature layer, add a new TEXT field to the attribute table that will hold the URL of the attached picture. Make it long, 500 characters.
In AGOL, add the feature layer to a map.
Start editing the layer.
Click a feature on the map to reveal the edit dialogue.
Right-click the attachment (i.e. “beaverdams.jpg”) and select Copy Link Address.
Click in the PicURL field and hit CTRL-V to paste the url.
Close the edit window.
Repeat.
Configure popups in the usual fashion using PicURL as the path to the image.
