I uploaded the wrong picture,how do I delete it?
If you do need a picture under this name but uploaded the wrong one, you can just upload another one on the same name and override the first.
The candidate for deletion template is for admins to notify the users about the upcoming deletion, not the other way around.
What do you mean I've been putting it on every file that needs to be deleted or have i been doing it wrong
Well, actually, maybe the admins on your wiki utilize the template this way, and keep track of it. But I don't think it's the commmon useage.
Click on the picture and press delete.
What do you think?
