Transparent GIF's

What does one mean by "transparent gif's"? Well a picture is worth a thousand words. Here's an example:

Non-transparent Transparent

So how is it done?

 Start up Microsoft Photo Editor.

 Go to File/Open and bring in your .gif file.

 Find the Set Transparent Color tool (the blue and yellow stick next to the black right angle, it's next to the sun shaped icon). Click on it.

 Then move the cursor to your graphic. It becomes a little black and white stick next to a right angle. Click on the background you want made transparent and then click OK.

 In the case above, it then looked checked.

 Save the now transparent gif. (File/Save).

Now insert this new .gif onto your web page as normal and it should be transparent.
