How do I set the icon from an OSX app to a button?

Hmm. Even after cleanup, am getting messages that my emails are too big.
What gives?

Shortened so that maybe i won't get a bounce.
http://en.wikipedia.org/wiki/Apple_Icon_Image_format is the source.

This is beyond me(and I no longer own a mac), but am I correct in assuming,
> the first 8 bytes (header) can be ignored, then the next chunk is an icon
