Thanks for the ideas thus far! I'm now thinking that it'd be easier to send the image as a bmp with run length encoding. I've found specifications for the format, but no C code that would take a bunch of 8 bit monochrome pixel values and turn it into a bmp. While searching around, I found a VERY EASY to deal with image format that can be read by Firefox. That format is XBM. It's only one bit per pixel, though. There's XPM which uses a color table, but it doesn't look like browsers know what to do with it. So, I guess I'll see if I can write some C30 code to take a 220x176 8 bit per pixel image and spew it out as a bmp.
