If a meme is pure information, then it's transfer from one medium to
another should adhere to the classical model of communications as
described by Claude Shannon. A low signal-to-noise ratio could be
responsible for the differences between the original incarnation of a meme
and the resulting neural representation of it in your head.
If you take a photograph and digitally scan it a hundred times--each
time using a lower resolution--at some point you'd have to agree that the
low-resolution renderings cease to contain the same meme. Again from
classical communications theory comes the classical answer: the medium is
the message. Our brains make great homes for memes but only the fittest
memes find ways to deal with the noise inherrent in their transfer from
one head to another and their storage in the neural machinery of the
brain. The fact that memes attenuate as they move through our senses on
their way to or from our brains is to be expected. The fact that many
memes exist which have evolved to thrive in this environment despite
this noise is also to be expected.
A painting might be a bad example. Think of the words "It's A Small World
Afterall". It's effortless to hear these words sung and then sing them
yourself in a way that would be easy for someone else to copy. The fact
that it's a small meme probably has a lot to do with that, as does the
"catchiness" of the song. If instead of a painting you saw a circle inscribed in a square, you would have an easier time reproducing high fidelity copies of it. Easier signal to make out, less prone to the same level of noise.
