$file->type = $request->type,

You are setting the path to the newly uploaded file within the if condition and then overriding it in the update statement with $request->image (probably binary image data). Plus there are few typos/syntax errors in your code as pointed out in comment.
You can try the below
public function update(Request $request, $id){
$file=File::find($id);
if($request->hasFile('image') && $request->file('image')->isValid())
{
//Validate the mime type, file size etc if required
//Store the newly uploaded image and get its path.
$path = $request->image->store('annonces');
//Delete the existing image
Storage::delete($file->image);
//Update the new path
$file->image = $path;
}
$file->type = $request->type;
$file->save();
return Redirect::to("file")
->withSuccess('Great! file has been successfully uploaded.');
}
