Q: Anyone else try to Share an image from Photos using El Capitan?

Worked for me. You should get a little, pop-up message window.

Did you try any of the others?

To anywhere, or just Messages?

I also have this problem. The Share drop down only reveals Notes, no Mail, airdrop etc. Still able to drag and drop into an email.

Spent a long time on the phone with Applecare but without success.

For missing share options, try this: If Share options or Markup is missing after upgrading to OS X Yosemite or El Capitan - Apple Support
