Gif Transparency help

I want to make a very simple sig, text only, no effects or anything. Basically, I just don't like the available fonts that I can use for an html sig on the board I post on ;p Anyways, I save the file as a .gif with transparency and when I tested it out in an HTML file, it showed up fine, but that was only with a white background. When I changed the background color to anything other than white, the text had white pixels around it. Could anyone give some pointers on how to get rid of those pixels around the text? It wouldn't be a problem if the board background color was white, but it's blue and it looks completely horrible. I also tried saving as a .png, same result.

if your using Internet Explorer......PNG's suck in IE, they don't support it - Mozilla does however.

try changing the matte colour of the GIF to the colour required. if you don't know the correct Hex Code just screenshot the page and use the colour selector tool in photoshop.

PNG's are the new GIFs but with alpha trans......GIF's are dying...just like HTML >.
