Thanks for your answer and sorry for my english :-)
My problem is a bit more complicate. I have a list of players (PLAYERS) and an asset library (BASEIMAGES). I want to associate the country include in the list of the player with the picture of this country include in the asset library.
First, I'm not sure that I agree to used Asset Library and no Pictures gallery ? I don't succed to do what you explain with this asset library !
@NickiGreene2 Can you copy and paste the image URL you are trying to use? If the image is privately hosted (i.e. requires a logged-in user to view, like most Sharepoint images), we cannot display the image unless it is a column in a table of an authenticated data source.
An authentication-required image may show up on your web browser but not on your mobile devices because your web browser saves browser cookies containing your authentication credentials, while your mobile device cannot save these cookies. Thus, on your mobile devices the images will not display.
@jdvroum You can create a SharePoint connection to achieve what you want here. Create a new list on Sharepoint with two columns -- one named "Player" and another named "Player Image" (you can choose other names). Then upload your images onto the SharePoint list as an attachment on your Sharepoint site. Finally, on your PowerApp, add your SharePoint connection to your PowerApp and bind it to a Gallery control.

@ergaMerci for your answer. I will try as soon as possible.

I was having the same issue... I had a gallery that displayed images in a SharePoint list. The images were on a remote server outside of the SharePoint site. I had a SharePoint list with a picture column. I used the URL for the images on the remote server in my SharePoint picture column. The images were showing in web browser BUT were not showing on mobile device.
I resolved it by uploading the images to a google sites and replacing the URL in the SharePoint list with the google sites URL and the pictures displayed on mobile device.
Not sure why the remote server I originally hosted the images on did not work for mobile device BUT google sites did work.
Try creating a google sites page and uploading the images there. Then use the URL from googles sites in SharePoint and see if that works for you.
Still having issues with Images not loading in PowerApps Mobile. One day they are fine, next they do not appear. I have noticed that the Tenant Blob Caches are having issues right across the board. Pictures on SharePoint Online Logos disappear (even after CTRL F5). I have issues pictures disappearing full stop.
