Even that is a LOT of data.

Keep the data simple. HTML with GIFs and JPGs, using gifs whenever possible. Smaller files than PDF- anything that you might want to do as PDF, try it as a GIF and compare sizes.

If it is to be downloaded, even 64MB is a LOT. It is a lot on broadband, and lot of people here are still on dialup.
