I love to see everyone's pictures in these forums so i thought i'd contribute some of mine! 
To see them fullsize just click to go to the flickr page, you may have to have a username there to see the blown up versions though. Wish i could have posted them a little larger. 1024 wide is probably too big and that was the only other option.
All taken with a Nikon D40x and the kit lens, 18-55mm f/3.5-5.6 with the occasional SB-400 speedlight. I think i've really pushed this lens to its limits for these kinds of photos...
