I've read somewhere (and I forget where and I've tried to find it again but can't, I just can't, damnit!) that Colin Newman himself has said most (maybe all?) the lyrics on his first solo LP, A-Z, where kind of toss offs ... words that sounded good at the time but not really intended to contain any carefully constructed meanings or deliberately underlying messages to decode. And so perhaps it's best to abandon any seeming allusion the fifth track on the LP might have to the same territory René Magritte staked out in his painting The Treachery of Images (and expounded upon in his much later, lesser known, just as interesting painting The Two Mysteries).
The whispered lyrics (see below) do seem to present a cryptic dialogue between someone inviting an exchange of images for a specific purpose of some kind with another person who resists the idea that such an exchange could have any meaning at all. The person resisting the proffered image then departs the conversation not markedly changed from the state they were in at the conversation's beginning (or "complete" as they insist). Odd. Perhaps Newman intended no deliberate meaning in these lyrics, but he tapped in to something that to my mind comes off much like a Zen Kōan. I can spend time contemplating what the non-meaning may mean.
The music emerges Zen garden placid and quite relaxed and relaxing until the chorus (chorus? I think that's what it is. I refer to where the song changes and, in the lyrics, the other voice of the dialogue comes in). After that we have a guitar (I think) with an unorthodox tuning played and recorded in such a way that we are reminded of a live mosquito trapped in our ear using our tympanic membrane as a punching bag. Despite it's gentle beginning, Image changes into something that can be difficult listening and it stays within the tense and paranoid mood of most of the other songs on the LP.
I'll show you an image
You show me an image
What does your image mean?
You won't play my game
But you know that a sequence
Of events is unfolding
Who said that?
You haven't the right
I came complete and I'll leave that way
