I used the "convert geotagged photos to points" tool in Desktop to create a feature class of garden objects with a photo of each one. Worked great. Then I created a feature service on AGO, and the images were uploaded to the cloud as attachments. Worked great. However, I cannot figure out how to get the attachment to show up in the popup any other way than a link. I would like a thumbnail of each photo that the use can then click to get the larger image. My workaround has been to add a "PhotoURL" field in the table, and paste the URL of each attachment, one at a time. Then I can use use this field in the popup configuration. Very time consuming. Any suggestions?
