Good morning, Bruce. You can upload any file type on UHH; it's the mb size that is restrictive. On a good day I've been able to load a 22 mb file, but generally it's closer to 20. File types such as raw, dng, pdf, doc and a few others will not present a thumbnail. We will see just the download link with "attached file" automatically included as a caption.
You could also use dropbox and provide a link.
Best to you!
I will upload to my google drive.
