JPEG Attachments Popup Preview not working

[malte]

Hello,

we have an issue with JPEG Attachments on Feature Services in Enterprise 11.2 not having a preview in Popups. It seems to be due to the REST API not being able to produce a smaller image preview when the "w" parameter is defined in the request (see https://developers.arcgis.com/rest/services-reference/enterprise/attachment-feature-service/). We have found this issue to be appearing with images from Samsung Phones, especially with Android 14. The REST API returns this error:

JFIF APP0 must be first marker after SOI

There are some old threads regarding this error message and they seem to hint towards the EXIF data of the images:

https://github.com/haraldk/TwelveMonkeys/issues/428

Interestingly, when we download an attachment where the preview doesn't work, save a copy of the image with the Windows default image viewer (and thereby modifying the EXIF data) and add the image as an attachment again, the preview works. We also don't have this problem with the original image added as an attachment to a feature layer in ArcGIS Online.

Has anyone had the same issue or can confirm it?

Thanks

Hi malte,

we have the same issue with Samsung mobile phones (Android 11 and 13) in Enterprise 11.1.

Images taken with iOS devices do not cause any problems.

We collect data and photos with Field Maps. In MapViewer popup the attached photos are only shown as linked container with text like "photo1". By clicking that container a new tab in the browser opens showing the image.

I took a look at the jpg files with Notepad++

Samsung jpg starts like that   ÿØÿáâExif MM *

iPhone jpg starts like that    ÿØÿà JFIF

H H ÿá

Other devices  I can not check as we only use iPhones and Samsung mobile devices.

Any solution or hint as where to change Enterprise Portal configuration our files would really be appreciated.
