You are selling yourself short! Use a better compressor than zip.
Whatever magic encoding you use (and I use the word "magic" deliberately)
produces lots of repeated strings so the bzip2 utility can take your 110K
text encoded image and compress it to just 228 bytes (yes 228). Imagine
that, a 183K palleted image compressed to 228 bytes entirely without loss
of data. [Actually, zip compressed it to 892 so I don't know where your
2K comed from -- maybe you thought <1K would look suspicious?]

When is the CACM paper comming out? ;-)
