10MB for 8 pages is too much....
normally one page is about 50kB, have a look at the patents....
did you scan them? scan them again in B/W save them as .gif or .png.
this formats need the smallest amount of space.
You also can have a look for the program XnView
which is freeware, and where you can easilyconvert from color to B/W or grey from .gif to .jpg.
If you need to break apart a .pdf look for Ghostscript/ghostview. With this you can convert from .pdf to .bmp and then with Xnview you can convert from .bmp- to .gif or .png.
But I think 10MB should be possible at my gmail account. I can convert that for you.
