I'm using the new Image Cropper API inside a controller and was wondering what the best way is to determine if an image has a crop or not.

If you call the GetCropUrl method and an image doesn't have a crop it will return the image url and some padding details appended: /media/1006/picture008.jpg?mode=pad. As a side note, I'm not sure if it should be doing this.

To distinguish between an image that has the crop I want and one without any crop at all I'm using the following code:

c var images =
    content.GetProperty("image")
    .GetValue<string>()
    .Split(',')
    .Select(id => Umbraco.TypedMedia(id).GetCropUrl("thumbnail"))
    .Where(image => image.Contains("=crop&"));

Note: I'm using the cropped images with a Multiple Media Picker.

Is there a better way to do this?
