Transparencies The first thing to do is to establish a background color for the image, and make sure that it doesn't coincide with any other color of the picture so that when we apply the transparency it will not change. After this, you can apply the transparency to the chosen color with any image editing program such as Fireworks

Transparencies A way to apply the transparency in Fireworks is through the buttons, these can be seen in the previous screen (in optimize image). When you are optimizing the image, you can click one of those two buttons, and the mouse will take the shape of a drop-count when placed over the image or over the image color list. By clicking on a color it will turn transparent.
