Seriously? Even I don't remember that. Haha. No problem. ;D.
Anyways, I think the easiest way would be to do a White-Be-Gone in GIMP, unless that's what you did. Another way, which requires a lot of patience is to use the eraser tool (GIMP, Photoshop, w/e) to remove the white background around the image. Save it as .gif for all browsers to see as transparent or as .png for higher quality but not all browsers will see it as transparent. D:
Hope I helped. ;D.
