Site Avatar Fail - possible to add directly to database?

Trying to use Site Avatars but images not uploading or saving after crop

other images for user profiles, and the default image for Site Categories upload no problem

if use regular upload and crop, doesn't save the image
if use alternative upload, doesn't save

However, it would actually be easier and better if could upload in bulk to database, especially if we could use CDN image URL

but since I couldn't upload any image to use to find it - I can't identify the table(s) where the image should go

can you please advise the table and parameters needed to upload into DB

or a fix for uploading...

I deactivated other plugins but still couldn't get it to work
