Show attached images inside popup with ArcGIS Online?

Question

In ArcGIS Online popups how does one display attached images inline as an image instead of just a link? In case of multiple images I'm okay with just first one showing inline.

Under "Configure Popup" checking " Show feature attachments as links" results in text-only links. If the "Pop-up Media" control is used to add an image, it shows inline, however one has to know the URL ahead of time. The drop down selector does not show attachments as a possibility.

Desired result

Popup showing 1st image inline, hidden beneath fold are rest of attachments as links.

Going through the same difficulty, I found a semi-automated solution that works as following:

1. The popup is opened and the attachment urls load and appear as links.
2. A placeholder image (an arrow in my case) is loaded where the image will soon load.
3. Clicking the placeholder retrieves the url from the attachment link and replaces its own source url with the retrieved url, making the attachment image show.

To make it work, put the following values in the popup image configuration:

• URL: data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAkAAAAHCAIAAABV+fA3AAAAGXRFWHRTb2Z0d2FyZQBBZG9iZSBJbWFnZVJlYWR5ccllPAAAADJJREFUeNpi+I8KFi1aBGczMWCAxYsXQxhY5ODS2OUg0jjlYmNjmXBJYDcTIgEEAAEGAGysItsbwoS/AAAAAElFTkSuQmCC (this is just an inline image of an arrow: you can replace it with any other url.
• Link: javascript:void(document.getElementsByClassName("esriViewPopup")[0].getElementsByTagName("img")[0].src = document.getElementsByClassName("esriViewPopup")[0].getElementsByTagName("a")[0].href); this makes the link run a javascript code that makes the (first) attachment link become the image's URL.

Hope this helps.

Another alternative is to use the new Operations Dashboard and add your web map to it. Pop-ups in the dashboard map will display all the images attached to a feature by default like in the image below:

I guess a potential workaround that would add a couple steps to your workflow would be the following:

1. Add text field [ATTACH_URL] (255 char) to the attribute table of the feature layer
2. Create a new point and upload the attachment
3. Click on the popup, then right-click and ‘Copy link address’ from the link to the attachment
4. Edit the feature, and paste this URL into the [ATTACH_URL] field
5. Configure the popup, and under Pop-up Media, click ADD>Image
6. Configure the popup as the following:

You would then have to repeat steps 3-4 every time you publish a new feature.

Not ideal or automated, but possible.

Here is a helpful GP tool that will add attachments to a pop-up:

The best way to do this is to use the "Pop-up Media" option under the "configure Pop-up" dialog within ArcGIS online for the layer you want to work with.

For the URL config you want to substitute 2 parts of the URL with {OBJECTID} like this bellow :

https://your.portal.url/server/rest/services/service_folder/service_name/MapServer/0/{OBJECTID}/attachments/{OBJECTID}?

This should give you the nice clean output you are expecting.

If your layer is hosted in AGOL, you can now use the map viewer beta and select the gallery option for attachments under configure pop-up.

This option is currently disabled for enterprise/portal hosted layers. An ideal workaround is to create a web app with the attachment viewer template.

If you're on an older version of enterprise (as we are) there is a bug where an attachment viewer app doesn't honour image orientation. The workaround I've developed, which may be useful to others in similar circumstance, is:

Calculate a field (using arcade) including comma-separated attachment IDs:

//calculate the attach IDs field
function IDs(f){
    return f.ID;
}

var Attach_ = Attachments($feature);
var AttachIDs = Map(Attach_, IDs);
return Concatenate(AttachIDs,','); 

This must be a field CALCULATE as attribute expressions do not currently support the Attachments function. I believe an attribute rule may also work.

Once the above is available, you can add attribute expressions in your pop-up (1 per attached image) as:

//build the URL for image attachment <ImageNumber>
var ImageNumber = 0
var AttachIDs = split($feature.AttachmentIDs,',')

if(ImageNumber > count(AttachIDs) - 1)
    return ''

var AttachID = AttachIDs[ImageNumber]
var BaseURL = "<your_domain>/server/rest/services/Hosted/LayerName/FeatureServer/0/"
var ObjectID = $feature.OBJECTID
return BaseURL + ObjectID + "/attachments/" + AttachID

ImageNumber must be incremented for each expression, starting from 0.

After that you can add an image per attachment as pop-up media, referencing the matching attribute expression for the url and link fields.
