How to upload a photo to a custom image field in a CDS entity? What is the difference between having a custom image field and using the Attachment control?

I have a CDS entity. It has a field named ReceiptImage. It is of image type. In my app I have a form that lets users upload a photo (just one) to the ReceiptImage field, but the photos aren't saving/uploading.

I hear there is an Attachment control but it doesn't seem to be an actual field in my CDS entity. Am I supposed to use the Attachment control in my Powerapps form to get the image from the user into the app, and then transfer that image from the Attachment control to the ReceiptImage field I actually want populated?

How do I get this to work please?

Hi @Lexicron ，

Do you want to update an image type field in entity?

Firstly, let me tell you the differences between the image field and Attachments.

Each entity has a metadata field called Attachments, which generated by system.

This field is updated by Attachments control inside a form.

And this field's data is stored in Note entity, not current entity.

While image type field is a custom field created manually.

This field could be updated by Image control, camera control, add picture control.

This field data could only be seen in powerapps.

I've made a similar test for your reference:

1)penimage is my image field

testmanies is my entity name

2)insert an add picture control

insert a submit button

3)set the submit button's OnSelect:

Patch(testmanies,Defaults(testmanies),{penimage:UploadedImage1.Image})

4)To view this field, you just need to insert a gallery, set the gallery's Items to this entity.

set an image control 's Image inside the gallery:

ThisItem.penimage
