Just my hopefull guess: Another theoretical possibility may be (I have not tried this yet) to upload your music
that you can use for listening or to use (embed) in the webpage. I was able to listen by downloading from OneDrive
but for embedding to webpage, I am not sure.
You can also approach your files (photo, music, or whatever) from your smart phone (I have not tried this yet.).

One thing you have to remember is that "when and if" you delete a file (such as a photo) in the One Drive,
the file will also disappear from the webpage because the original link is deleted.

1. Type www.onedrive.com and you will be in your own OneDrive. You may have to log in.
2. At left column, you will see a series of subdirectory, such as files, recent, photos, and etc.
3. For example, you click "Photos" in the left column, you will get the whole photos you uploaded in the OneDrive.
4. In this photo subdirectory of OneDrive, you can do the following maneuvers to embed pictures to the webpage.

It is not a difficult thing to do. Once you do a few, you can get it done without referring to my writings.

1. First you open your OneDrive and go to the Photos subdirectory. Of course, before that you have to upload your pictures first,
or your pictures may get automatically uploaded in OneDrive. They may be there already, at least some of them are in my case.
2. Pick a picture you want to embed in your webpage and left click it.
3. Then the picture comes out in it's original size (not the small one at the first screen) in black background.
4. Put your mouse on the black background, then you will see a series of menu at the top row.
They are almost full editing function and some more.
5. Among these, pick and click " Embed".
6. A new panel opens at left edge with a URL for the embed code.
It is a very long URL. This is one bad part of using the One Drive.
7. Checkmark at "Include HTML tags", and then you have the full embed codes in the box.
The whole thing looks like this for one picture: https://usp5oq-ch3302.files.1drv.com/y3m9KAPqb-Mx1GhhTzf-c6cTCuD44C974BlXjCHV9ljCkiZvxplbXpLDavwhs9FdVp5UVER-BBBeZuWSwUoUBWOSaVxg4JUuTcoCdGegRFCbj3Oj-nCFKPLHJCzPQpqtRlny6P6rEgvneu1shJCGHey1Q?width=1366&height=426&cropmode=none" width=800 height=250 />
8. Copy the whole thing in the box. And "Paste" it in your webpage code area.
Please note that it must have "width and height" in it. Without it, it becomes "width=0 height=0".
Don't forget to include width and height, otherwise the picture may come out as a small empty box.
This may be the main reason we fail to embed pictures from other photo websites.
9. Also, you may specify the size to fit the webpage if the original is too big for the webpage.
Here, the original size is 1366x426, but I used "width=800 height=250" to fit inside the webpage.

Don't forget to add texts on the page, otherwise you get "No Content" message.

Please try my suggestions  (I was successful as you see here) and let me know if any success or failure.
