Moring all,
I have a page based around a grid, as shown here: http://www.holtworth.net/tht/index.php.
Some of the grid lines are the white background showing through spaces between the divs, some are part of the image.

They don't line up, even though they were all created in Illustrator and cropped pretty accurately in Photoshop, and placed using CSS

So,
  • Is there a way to crop images in Photoshop to exact pixels?
  • Is there a better way of creating a layout like this?
