GetSpriteXY
I was working with some css sprites in a project. There was sprite with lot of small icons. It was difficult finding the position of icons inside the sprite. I used to open the sprite in Photoshop and find the X and Y position of the icon needed. And this position was used in the CSS class. To make the process simpler a tool was created where you can upload the sprite and using mouse draw a box around the icon. The tool will generate the CSS style for you.
