Append slice instead of individual elements
Append slice instead of individual elements

Here we append the args[2:] slice to imagesNames. Note, args[1], which
could contain a remote name is a special case which is handled earlier.
For args[1] we first split the remote and image name, and add just the image
name to imageNames slice.
