I successfully self published 2 picture books with Inkscape .45 and Scribus 1.3.3.8 from photos and drawings I created. I did that on Xubuntu Linux although most the drawings were designed on Mac OS X. Inkscape was used to vectorize the images and Scribus was used for layout. I have already seen the print outs and made them available through Lulu.com - they look great. I have previously published books through Lulu.com using LaTeX. The covers for all the books were designed in Xara Xtreme on Xubuntu Linux. The print versions are being sold at cost.
