weird smudge in pictures nikon d40 *pics*

[mercury52]

I wasn't sure what to do after spotting this smudge on the right side of all my pictures. I tried cleaning the lens but that didn't help. After I googled the problem and came up with this forum post I tried it and IT WORKED.

Thanks to all in this post that gave answer of locking the mirror and blowing dust particles from it. When I locked the mirror I could actually see the dust particle. I used a small ear plunger bulb to blow air into the area and it got rid of the dust.

I'm good to go....
