Having Difficulties Trying To Delete Images

Hi all,
I'm trying to delete some image objects I have imported as background images but seem unable to do so. I have tried both selecting the image/pressing delete and trying to drag the image down into the trash can but neither has worked.
Just checking where I am going wrong?

 

Figured it. Didn't realise I needed to make the backgrounds visible in order to delete them

 

Hi @MattGamer, you need to uncheck the "visual" cross next to it before you can delete it. Items also need to be unlocked before they can be deleted.
