Powerapp doesn't show images on Teams, but does on Webapp (thumbnail function or not)

[Aldebs]

Hello all, 

I recently tried to implement pictures in an APP with an SP list. 

First, I tried with a Text column, where I included the link redirecting to a Onedrive folder (unlocked for everyone within the entreptise). We are able to see some pictures, but never on the Team Powerapp host, only by internet access. 

Second, I tried with a text column, but I took the link from share item function. Simply didn't work (Team or Internet app). 

Third, I tried to use an Hyperlink column, couldn't make it work either (Team or Internet app).

Forth, I tried an Image column, where I uploaded some pictures. Still, Team or Internet app. I tried with the functions:

'Gallery'.Selected.'{Thumbnail}'.Image, didn't work.

ThisItem.Thumbnail.Image, nothing. 

ThisItem.'Thumbnail'.Image, nothing.

ThisItem.'{Thumbnail}'.Image, still nothing.

I went back to the first technique, because at least, it displayed something on internet, but this APP is designed to work through teams, and not on internet. 

I also tried to look for access, but it didn't seems to be the problem (a few people have the same issue with different levels access). 

Does anyone has a solution for this ? 

Thanks in advance.
