Not able to show image thumbnail in Powerapps

Posted on by PHNN

Hi Team,

I have a sharepoint list from which the data is sourced for one of my canvas app, the issue is that using the following formula :

First(ThisItem.Attachments).Value

I am not able to show the thumbnail (or image preview) in the app, is it something to do with the organizational policies ?

Because the same formula is working on all other apps built on different tenants/environments.

PS : I faced this issue as well in one of the flow - not sure if this has something to do with the above mentioned error

Hi @PHNN ,

What type of file is it ? Only Image files will preview from Attachments.

I would suggest you talk to your system admin on the second one.

Hi @WarrenBelz ,
Yes it is a .png file

Since i am not able to display image from list i was trying to move it to document library using flow and then show it from there and the second error i have shown is related to that.

Thanks

Hi @WarrenBelz ,

Thanks for the link and response.
I have checked all the applicable methods in my scenario as mentioned in that post but still not able to show the preview of image.

Do you think this has something to do with the organizational policies ?

That was my initial thought and I believe it is the case.
