Hello,
I have need to extract an image froma a white background for place
this image on a black background on a flash file.
The problem is that there is a white halo that is ugly to see.
I heve tried to select the white colors, on Safe for web command, to
render transparent but the result is not fine.
There's a solution?
I hope of to have been clear and sorry for my english... :-)

Hi Freddie,

There are quite a few solutions, as well as ways of extracting your original
image. If you started out by using the magic wand, as many people do, that
could be the source of the problem.

Photoshop's Filter>Extract... command can do a beautiful job of removing the
original matte color, so you may want to check out a tutorial on the correct
use of that command. If this is not relevant to your problem, or otherwise
does not improve things, there are at least two commands may help with this.
First get your extracted image on a separate layer. Then use one of these
two procedures

1) Layer>Matting>Remove Black Matte - will quickly remove the black for most
cases. It will fail if the layer has large feathered edges.

2) If that doesn't work, use Select>Load Selection... to load the selection
from the transparency information of the extracted layer. Then use
Selection>Refine Edge... and click on Preview. Select the icon for a white
background, and use the various sliders to adjust your selection. Once you
have it looking good, click OK, invert the selection and press the delete
key to clean up the layer. This method has the problem that you are
deleting part of the edge to get rid of the black fringe.

If none of the above methods work, there are any number of techniques that
might work for your particular image. I suggest that you post a sample of
the image for people to look at and make more specific suggestions. If
necessary, join Flickr.com or a similar site, post your image, and provide a
link to it here.
