Hi guys,

What's the best way to rename an image on upload? I'd like to prefix image names with a unique id which matches the related dataobject's ID as they are uploaded.

These images will be downloaded via FTP to perform bulk actions against after a period of time, and they need an identifier to link them to the dataobject with which they were uploaded.

Okay, so I was able to do this by extending SimpleImageField (which extends FileField) and overriding FileField's saveInto() method like so:

public function saveInto(DataObject $record) {
     $id = $_POST['id'];
     $filearr = $_FILES[$this->name];
     $ext = explode('.',$filearr['name']);
     $filearr['name'] = $id.'.'.strtolower(end($ext));
     $this->upload->loadIntoFile($filearr, $file, $this->folderName);


It works as I'd like for the front-end form, but isn't ideal as if images are uploaded via ModelAdmin, they're not renamed, so would appreciate suggestions for a more robust solution.
