Unwanted Sprite Movement

[atomicmidnight]

I am having an issue with a sprite sheet I made. When the sprite is moving, it seems to jerk or slide around as if it can't stay in place.  I am not sure why it is moving like this, but if anyone knows of a solution, I would appreciate it.

Thanks, and sorry if my question doesn't make sense(I'm not sure how to accurately describe the problem).

Your sprite images simply aren't aligned properly. The one in the top right corner needs to move a pixel to the right.
