To further help explain this. In almost every image editor i have used in order to put a transparency on a gif, when saving the file there is usualy a option in one of the save dialogs that is something to the effect of a check box for transparent back ground and then a way of choosing the background color to make transparent. In photoshop there is a colored box that you can click and then that pops up a color picker window that allows you to choose the transparency color. This option is only available when using a format that supports transparent bg's.
