All icon images that can be found on DT are almost uselss because the background is not transparent and it is dithered by the file size reduction and jpg compression.
So when attempting to remove the background of an icon to make it with a transparent background to be used on a web site (I use Photoshop magic wand selection tool) the dithered pixel around the border of the icon produce an horrible result.
For example a red icon on white background, levaes a red dithered dots around itself aftre the background was removed.
Does anyone know a way to remobve the icon background in a better way? Otherwise icons on DT are useless unless we have a website of exaclty the same background color used by the icon image which is quite diffcult.
I think, the best way for usable web-icons are vector-files. You can scale them in any way without loss of quality and you can use them in vecor format in flash or export as gif/png with transparent background. I upload web-icons always as Illustrator-additional-format
