Now I accidentally moved the pic across the screen and can’t get it back. I know about moving the sliders to make it bigger view but i actually moved the image to the side accidentally. How do i put it back in the middle? 
Hi Curaduk,
Use the Actual button in the Zoom Palette. (You can use the space bar to move the image manually.) Also, try posting questions about ZBrush in the main forum. You’ll get more responces.
