After making the background transparent, can I...
After using these instructions (below) for making the background transparent for my logo, their is still a bit of white around a small section. Is their a way to remove the left over white?

- use select by color tool, with treshold of 0, no feathering and no antialiasing. Click on the background. This will select only pure white pixels in the background
- grow the selection by 2 pixels. The selection now includes the background, and the border pixels (anti-aliasing)
- use Color/Color to alpha with white (it will only applies to background and logo border)

If this happens, your original background wasn't uniform (or was "dirty", with Jpeg artifacts). You can redo the whole thing using a higher threshold (with the Select by color or the Magic wand)
