Try using a camera with the macro setting on, that way you can get clearer pics. You can insert the memory chip into your computer in order to post on the forums 
(Just be careful to remove the chip the right way or you might accidentally delete the memory) That's what I used to do, though now I use my mom's phone.
Here's another thing. I use the Windows Live Photo Gallery to adjust the contrast (makes the gray lines appear blacker, which is very good) and highlights (to make the black areas even darker). Sometimes I have to adjust brightness to keep the picture from getting too dark.
