How to add photos to existing Online Layer.

Question

Hello, 
I'm new to Arcgis Online and I feel like I'm taking crazy pills. I'm just trying to add photos to already existing points in a layer. Although I'm the creator of the layer I can't seem to add these photos. I've tried altering the attribute table in Arcpro as well as configure pop-up. When I click on a point and try to edit the pop-up it seems as though I can't add any photos.

I have over 2000 photos to link with 2000 points (feature layer in ArcGIS Online). Is it possible to accomplish this in batches or similar to FME? I have an Excel file for the join, but I'm unsure if it will work or not.

@BECQ , a couple of troubleshoots:

1. have you enabled attachments in AGOL yet?

2. As @PeterMacKenzie2  said, you can assign attachments in the attribute table by RMC'ing. You can also open the Attributes panel from the Edit menu in Pro...

...and then add attachments there:

3. But if you're looking to do this in AGOL, you can add attachments via the Data tab from the Item Description menu:

4. Or if in a web map, you can edit features or add features and add attachments from the editing popup:

Are you talking about adding attachments to an AGOL hosted feature layer within Pro?
What steps have you tried?

I'll take a guess -

Here is a screenshot of the Add button. You get to this by right-clicking a row in the attribute table:

Hope that helps.
