djpate,
welcome to
RP.
the first thing is to convert this file to another format so it can be worked on more easily. i use paint shop pro so i changed it to their format to start with.
then, increase the color count to 16 million color to get rid of the limitations of a fixed color palette.
then, in
psp or photoshop, use the magic wand tool set on a very low tolerance and set to detect 'lightness' and click on the white area. this will select all the white area in the logo.
you can then either use the eraser and get rid of all of this and leave the background transparent, or use the fill tool and add a different background.
now, you could just use the fill tool without using the magic wand, but i didnt know if you wanted the bg transparent or filled.
once you have either removed all the bg or changed it, save your image and then save again as a different file type that you're going to be using on the web page. so, if you need it as a .gif simply save it again as a .gif.
you might also want to select out a tighter area for your logo. simply use the selection tool for this and then make a new image from that selection. you can do this before you use the magic wand or even after you've changed the bg. i'd do it before changing the file type back into what you're using on the web page, though.
