Allow Images stored on authenticated Sharepoint and Onedrive in Dashboards

Amazed/Appalled that this is explicitly not supported.

The company I work for are a full Office 365 E5 subscriber and use all the Microsoft tools.

It seems that Power BI does not allow images stored on Sharepoint and Onedrive (unless they are shared anonymously which the business doesn't allow for security reasons)

At this link under images:
https://powerbi.microsoft.com/en-us/documentation/powerbi-service-add-a-widget-to-a-dashboard/#add-an-image

It says, "Say you want your company logo on your dashboard, or some other image. You'll need to save the image file online and link to it. Make sure special credentials aren't required to access the image file. For example, OneDrive and SharePoint require authentication, so images stored there can't be added to a dashboard this way."

Worse, it is not fully "not supported" as it works perfectly fine in everything except IE. If I use "get link" from sharepoint on an image, it shows correctly in all browsers except for IE10. This means we are unable to put any images on any of our dashboards which is a pretty embarrassing conversation with our senior managers/directors that Microsofts own service doesn't work with other Microsoft services.

Surely this can't be that hard to just make this work in IE and job is done?
