Parameters

object $file File object:

string $dest destination directory to move the file to:

int $replace files move action:

string $presetname Imagecache preset to perfrom on the uploaded image.:

bool $delete_original A flag to tell the function how to handle: the existing file when it is deleted or replaced. This is used to prevent the status flag being set to temperory when the file is still used by the system somewhere else. For example, if you are saving a new node revision, with a new file, you would want to ensure that this is set to FALSE if the old image is still valid for some other revision.

Return value

int The {files}.fid or 0
