Did you try saving it onto your computer?
Usually it's something like putting your mouse on the photo and right click > save picture as. Then save it somewhere, like the desktop, so you can find it easily.
The open the file on your computer. Depending on what program you use to view photos, you may be able to enlarge it or get the contrast higher so you can read the labels on the fuse box.
And yeah, my local library lets me connect to Chilton's online for auto repair stuff. My last library used the Auto Reference Repair Manual, and it was better for wiring schematics. So it'd be worth a call or web search on your library.
The Online Repair Manuals discussion in the forums has some repair links too.
