Now, I am using svg output, which works. But PDF would be more convenient.

BTW: I do not like the fact, that edges are going cross the images. I do not know how to draw them in background. (But this is not a bug, I posted the question to forum)

The color corruption problem is caused by using gd to load the jpg with a limited 256 element indexed colortable. It works ok for single images, but completely runs out of colors for large sets of different images.

There doesn't seem to be a better jpg loadimage plugin available at the moment. I'll see if I can provide a better one at some point...

Meanwhile, using png seems to work better. I tried by converting your images with "netpbm" tools:

    cd patches
    for i in *jpg; do jpegtopnm <$i | pnmtopng > ${i%%jpg}png;done

and then edit the .dot file to refer to the .png instead of the .jpg

Edges can be drawn first (underneath) by using: graph [outputorder=edgesfirst]

There is a new jpg image-loader provided by the gdk plugin. If this is available it will be used in preference to the one provided by the gd plugin.
