It is also very hard indeed to recover the image of James Brown out of 64 byte.

You just need a specialized compression algorithm. I have one that can reconstruct an image of James Brown from a single bit.

Here's the pseudocode for the expander:

if first bit is 0

return hard-coded James Brown image

else

remove initial bit and pass remaining data to gzip

Extending this to support an image of Barry White is left as an exercise for the reader.
