Where are my pictures stored?


I am trying to delete old unused pictures form my webstore so I was looking for the “customcontent” folder in my FTP but I can’t seem to find it. This is the path to a picture I uploaded < img alt = “custom image” src = " / store _ images / customcontent/campaign.jpg" / >.
The problem is that I can’t upload new pictures which name has already been used in the past and this is becoming a problem.
