How can transfer files (mainly images) from OneDrive to my Xbox One S?

Yes, it seems that this is not working properly with OneDrive and other cloud sites, probably a recent update change the way that websites works on Xbox.

I tried to do the same, and now is not letting me do it :c

Even I downloaded a photo couple weeks ago :c

We may need to wait until a new update appears to see if we are able to download images on our consoles again :c

In the meantime you could share this feedback with Microsoft using feedback portal:

How?

Because when I try to download a image on Microsoft Edge (on Xbox), the browser says 'Downloads are not supported on this device'. I believe it use to let me do that on the old Microsoft Edge. But on the new, Not anymore.. 😔

Hope you're doing great today buddy

Usually for me the most quicker way is open one drive page on Microsoft Edge, then sign in my account and open the picture that I want to use on another tab and save it (or set it as background if needed)

Yeah, even I wasn't aware of this change Meanie :c

Sorry

I do have it downloaded, But I can't find the download button on here, It's either the my OneDrive might be outdated, or I just don't know what I'm doing.
