Images are stored in RTF in very nonoptimal way.

True color bitmaps are huge by themselves (1024 *768 takes several

megabytes), and they are doubled in size in RTF (because each byte is

encoded by two hexadecimal digits).

Suggestions:

1) Use Png instead of bitmaps.

2) Always call RichViewEdit.DeleteUnusedStyles before saving to the field. A

number of unused styles increase data size and slow down loading and saving
