(images via my camera)

Note:  I’ve been having a bit of trouble for a while with my camera as well as the post-editing.  They look fine when I resize and edit via photoshop but the second I post them on here, it seems to all go away and look blurry.  Does anyone have any tips for me?  I use a Nikon D40 and do most of my editing on Bridge and Photoshop.
