I ended up using MS Onedrive for now. I uploaded my photos to the photos section. From there, at least what I've found, is that you can't use the Windows 10 app (in your taskbar next to your clock) to share the photos but instead go to their webpage (login of course) and click Embed. From there, click Generate.Do not include the extra HTML tags as they're not needed. Copy the text in the box with the code - all of it.
Now in your reply click the underlined A in the upper right corner to go to Advanced Mode. Click the little image icon (if you hover your mouse over it it pops up Image). Paste all of the code into the URL line and you get the below results.
**Depending on the size of your original you may have to use the drop box to change the image size to something the forum can handle. This is Medium and my cell camera is set to 16:9 (16M).
And my cell, Galaxy S6, includes the ability to upload directly to OneDrive.
