Load an Image in a block (in edit mode) on load

Hi,

I am kindly request your help for me to get an advice to load an image on load in a block in cms edit mode. 

Scenario: I need to do a block for editors to create hotspots in an image. 

My suggestion to create 2 block types where 

Block 1 (InfographicBlock.cs): image (Content reference) as required field with a content area to hold hostspot areas.

Block 2 (InfographicHotspotBlock.cs): will load above loaded image on the block for editors to create hotspot.Simple 1 point (x,y) only. 

I am reading parent block’s (Block 1) image details to Block 2 by using following code : 

[Ignore]
public string DeskTopImageURL
{    get {        var contentRepository = ServiceLocator.Current.GetInstance();        var data = contentRepository.Get(((IContent)this).ParentLink).CreateWritableClone() as InfographicBlock;        return !ContentReference.IsNullOrEmpty(data.DeskTopImageURL) ? UrlResolver.Current.GetUrl(data.DeskTopImageURL) : string.Empty;    }
}

Can someone suggest me a suitable method to load that image in Block 2  in edit mode for editor’s to create hotspots. Any help would be appreciated.
