Removing the grey box below a picture

Hello,

Thank you for this galery.

I was wondering how to remove the grey box below a picture, where it is written “delete” and “edit” for administrator and empty for anonymous users. It is useful for administrators but quite unaesthetic for anonymous users to see an empty grey box below each picture.

I tried to find where to fix this in the settings but did not succeed to find out.

Any help would be appreciated.

Thank you 🙂
