IKImageView get image frame

Question

I can change position of Image inside IKImageview and also I change image, when next button is clicked , but postion of Image is reseted.... I need to get information about old position of the Image , but haven't found any solution yet.

Here is code of how I'm trying to change image:

RightImage.SetImageWithURL (NSUrl.FromFilename (_rightImagePath));

RightImage view is outlet from storyboard file

[Outlet]
        ImageKit.IKImageView RightImage { get; set; }

for example I have loaded the picture and then changed position of it with mouse movement :

after this I've just changed image (with url - code is above), and position of image was reseted to the default one :

So, my question is, how to get information about Image frame or coordinates inside IKImageView ? Or how to change image without changing it position ?
