how to change the administrator of my computer back to me

I registered an Apple id for my husband and made the two of us family members using my desktop. Now my computer has made my husband the administrator of my desktop and I have to sign in with his photo on the screen. He has his own computer.
How do I change the Administrator back to me?

Open an elevated command prompt from his account (press start button, type cmd, right click "Command Prompt" and select run as administrator)

• Type net localgroup administrators /add <yourusername>
• Log out and back in, your account should be a local admin account now.

If you don't know your account name type net user​

If you mean you can't see how to find your account to sign into, then look at the lower left corner of the login screen. There should be a list of available accounts there - just click on yours.

There is just a photo of him, his name, and email address with the login bar. Nothing in the lower left.

Sounds like the only way to get in and change things would be to temporarily enable the built-in Administrator account - and to do that, probably the only way available to you now would be Option 4 here...
