I created a hosted feature layer from feature class with image attachments by ahring as web layer in Pro. In AGOL popups the images shared from Pro show up only as links and must be clicked and downloaded to view.
In the same HFL, on records collected using Field Maps, the images display inline.
How can I make attachments added via Pro appear inline?
I have some further info on this issue. It seems that images attached through Pro are getting the MIME type "application/octet stream" while the type image/jpeg is needed to display inline in the popup.
