Replacing pictures.

There’s a slight error in one or two of my pics I’ve recently uploaded but I don’t see a way to replace uploaded files.  
Shall I have to simply delete and re-upload the pictures?

Upload the corrected images, and if the automagic deduper doesn’t make a dupe report, feel free to make one yourself on the relevant images and the staff can merge them as needed. (or report them anyway so that we know which one is meant to be displayed)

Think I might have cocked it up, we’ll see.
