Help with removing a picture/image from art board!

Hello,

I am wondering if someone can assist me in removing this screenshot / picture from the artboard. I can't highlight it or select it at all and im not sure how to get rid of it. Every time I add new artboard and rearrange them it just stays in that same position.

Please have a look at the screenshot here https://imgur.com/a/bjbaFhK

I am not an adobe illustrator guy so please forgive me if this is something relatively easily to do.

Thanks in advance!
