Is the image layer correctly displayed on the map ?

Does is works if you don't set a custom size for your overview map ? 

I never use the Image Layer but the 'options' parameter seems to be wrong,
try with:
var panorama = new OpenLayers.Layer.Image(myImage.name,

Also check your parameters type: 
  myImage.name : String
  myImage.src: String
  panorama_bounds: OpenLayers.Bounds
  panorama_size: OpenLayers.Size
