the image plane thing.. you can find them in the hypeshade under 'cameras' (or was it textures?O_o) there you can select and delete or edit em as you want..

you can find them in the outliner and hypergraph too if you uncheck 'show dag objects only' in the outliner or select 'display > display shape nodes' (i think) in the hypergraph
