AutoCAD .NET :: Iterate Through Raster Images / Image Dictionary

Here's the Code I have so far: 

I want to iterate through the Image Dictionary and Connect into the Raster ImageDef Properties. 

I want to be able to modify and fix missing Raster Images. 

How to get this code sorted out. 

For Each myObjID As ObjectId In myModelSpace
Dim myEnt As Entity = myObjID.GetObject(OpenMode.ForRead) 
If TypeOf myEnt Is Image Then Dim myRasterImg As RasterImage
Dim myRasterImgDef As RasterImageDef 'Open The Dictionary
Dim ImgDict As ObjectId = RasterImageDef.GetImageDictionary(DatabaseIn)
For Each dictEntry In ImgDict NextEnd If
