Sharepoint images not rendering in Mobile App

[SimonP19]

Hi, 

First time I make a Mobile App with images in it, however they do not seem to be rendering when opening the app(they appear just fine on my computer). I'm connected to the sharepoint app on my phone and sharepoint website, but not much is happening. 

Is there an extra step in the Power Bi app I'm missing to connect to Sharepoint? 
I'm using the Sharepoint.Contents to create the URL link that generate the images in PB. 

Thank you,

General guidance is to avoid linking to images on sharepoints due to all the issues with authentication. Instead pull the images into your Power BI dataset during the refresh, store them as Base64, and then reconstruct them in DAX.

Thank you for the suggestions, I'll look into this solution. Do you know by chance the average size of an image when stored in Base64, then rebuilt? I have hundreds of 300KB to 1MB images.

Base64 is an encoding, so the size would be the same.
