Ok sorry then, I wasn't sure if Philip was dealing with the same issue.
So, to explain my problem :
I created a first inquiry few month ago into "Survey123 Connect", in which the users had to fill informations and to attach 2-3 pictures (type "image" in xlsform).
The thing is that I had to make an upgrade of the inquiry and to add some fields, but it appeared that I lost all of my attached images.
Fortunately, I had a copy of those pictures, so I just needed to edit the previous features and to attach them. I didn't find any way to edit images in existing features via Survey123 (mobille app or survey123.com), so I decided to proceed by using Arcgis Online. The thing in proceeding that way is that in Survey123, my pictures doesn't appeared as "Photo1", "Photo2" and "Photo3" anymore, but as "Attachments" (see Annex 1). Only new encoding , as shown in Annex 2, acts correctly.
It's not a huge problem as I can consult the pictures anyway by Survey123.com. The issue is that I can't find a correct way to insert the attachments into a report. I saw a few discussions about this, but I never managed to find a correct way to export correctly all the attachments into the report generated (Annex3), but only get one of them.
I'm not sure I'm getting clear enough?
Anyway, thanks for your help!
Quentin.
