Ray,

Magic!

What I do is I combine the JPG's in Acrobat to create a single file for each article. The file size ends up being about the size of the combined original JPG's. But the PDF at this point is nothing more than a package of raster files. If you ask Acrobat to "reduce file size" (in the Document menu), it will examine the contents of the raster images and vectorize them. In the case of B&W text it is quite efficient at making compressed images like JPG's even lighter once vectorized. The size of the file reduces to about 40% of the original.

The PDF's end up having a bit of a "bleed" in the text due to the JPG compression but I was able to upload all three articles in one shot as they were under the 6 MB limit combined.

Are you scanning directly into JPG or into TIF or PDF? If you scan into PDF, you can still reduce the file but it might start off being reasonably light (unless the scan quality settings are set high)

I hope this helps, David.
