Hope someone will help

Maybe because your image have blurry edges. Try to make the edges exactly in pixels, or in example if you want to make a blurry drop shadow effect of an image, make a new layer below your original/shadow layer and make a 1 or 2 pixels outline using the background color of your web page. It works for me! or you can mail me the image so i can make the gif transparent for you and write you the step by step so you can try it your self.

keep on tryin!

A transparent .gif or .png must be an indexed color image. Try converting it to indexed color *before* saving it as a .gif, the non-transparent area may be obvious.

Or, just re-open the .gif and look at it, you will see the non-transparent line and be able to determine what's doing it in the original file.

If it's a soft edge around the non transparent part of your image that is actually what you want it to look like unless you're trying to make them for multiple colored backgrounds. I don't have CS but in my image editor I can and do produce this on purpose. The soft edge smooths out contrasting colors between your gif and the background color. If you don't any imges that have a very high contrast with the background will appear very jagged or aliased on round edges or angles.

A good example of this is the smilies common to many forums, they have sets for light or dark backgrounds. The key is getting the correct color soft edge.

The reason that happens is because of the Matte colour.

When you are saving for Web & Devices, on the right hand side you will see Matte, click on this and select none. Then your outline will dissapear!
