a good method but many image formats are supported
a graphic format that will allow you to set all pixels of a certain color to become transparent when your graphic is placed on a background on a web page
an image (a gif file) that will blend in to any background color
an image that lets the background show through selected parts of an image
a normal gif image with the exception that you assign one of the colors in the image to be transparent or clear
a type of GIF image in which we set one or more colors as "transparent" or "invisible" (if you like)
A GIF that has one of its colors set to be transparent. When displayed against a background tile or color, the image will appear to float above it.
A GIF image that appears to float directly atop a Web page without its own background or border. A specific number in the GIF color palette (#89) is assigned to be the same color as the background of the page, giving the image a transparent appearance.
A GIF image wherein a color, usually the background, has been selected to appear as transparent. Placed on a Web page, any background color or tiled image will show through the GIF. Transparent GIFs allow the use of graphics with shapes other than rectangles.
A type of GIF image where one color, usually the background of the image, has been selected to appear as transparent.
A feature of the GIF89a image file format that lets a designer designate one color in the image's palette as transparent. This enables the background to show through designated parts of an image.
Transparent GIFs are useful because they appear to blend in smoothly with the user's display, even if the user has set a background color that differs from that the developer expected. They do this by assigning one color to be transparent -- if the Web browser supports transparency, that color will be replaced by the browser's background color, whatever it may be.
