In order to load image quickly in webpage, we merger many small images into a big image and use the following css to show certain small image.
Is there a free image editor software to add, edit or delete a small image in big image?
Thanks!

It’s called sprites, the technique to add many images into one.
This looks like a good tool: http://spritegen.website-performance.org/
