Delete bottom sublayer / remove embedded image

[BrianZebra]

Hello, I have an svg file with 1 layer and hundreds of sublayers.  I'm looking for a way to delete the very bottom sublayer with a script - the bottom layer for the documents I have is an embedded image I need to remove.  I know this is sorta asking two different things but either would solve my dilemma.  Any help would be greatly appreciated.

Something like this?

activeDocument.rasterItems[0].remove(); // works when only one image existing in the document
