I have a question on email addresses and scammers, can you help?

Hello,
I need some techie help. I belong to a language exchange program. Recently, I had a language partner ask me to send him pictures of my paintings to him with my email (the site is not friendly for sending photos). I have two email addresses. One is associated with my banking/personal credit card information, and the other is not. In other words, I have never put down that email address (a gmail account) in any of my personal banking and it's not associated with any credit card. If I send this person my pictures, and I use the gmail address NOT associated with my banking/credit card information--is there a chance (assuming he is a scammer) that he is still able to access my personal info?
That's my question in a nutshell.

Good news. It went well. I mistakely wrote this person on my regular email address, and he finally was able to connect with me on Line wirth no problems. All is good, thankfully.
