[Scribus] PDF file size

[Paraplegic Racehorse]

Scribus 1.2, SuSE 9.1 Pro

I am in the process of creating some PDF documents of several series of 
disparate, but themed, graphics files. I am unable to achieve anything 
resembling reasonable PDF output file size, however. In one case, I have 
somewhat less than one page of text (two fonts, embedded) and 
approximately 12 pages of assorted graphics files. Within my filesystem, 
the combined size of all the graphics is about four MB of [mostly] 
reduced-color-palatte GIF files. The output PDF, however, is nearly 
20MB! (8.0 x 10.5 pages, 300dpi, reduce images to 300dpi, embed two 
fonts, Acrobat 5.0, generate thumbs, include bookmarks, format for printer)

The only thing that immediately comes to mind, concerning how to reduce 
file size is to reduce the resolution, which I am loathe to do. Can 
anyone toss me some pointers?

Incidentally, the first four of the PDFs are available at
