Thank you for coming to the community with your suggestion! You are correct that you can not delete an image out of your account from within a campaign. However if you go to the 'Library' tab at the top of the page, you can select and delete images or documents from there. I can definitely pass on your suggestion to make deletion possible from within a campaign. If you have any other feedback or concerns, please feel free to share them here so we know where we can improve!
