May I know what do you mean by "for attached GIF" ?

Please have a look at the first image that I have uploaded, the white portion of the background is what I mean by non-transparent background. If it is transparent, then it will be replaced by any background (color or any pattern) that the GIF is being placed on (e.g. if the GIF is placed on application desktop which is covered by a wallpaper)
