Ok, thank you guys!

I don't think we can help you there. Your best bet would
probably be to rescan the picture and try to make it show up
better.

Well, you can't do much about that except PM a mod to ask
them to change your gallerie entrance picture to something
else or keep it as it is now.

Well, you can always use an editor to make it darker, or ask
someone who CAN to do so. I am sure people don't mind. It
only takes a few moments, I know becuase I have done it
before. So make the outlines darker, send it to the site,
and then request for it to be changed. Thats your best bet.
