The problem with GIF images are that there is no standard editor that comes along with the operating system which allows you to edit any of the frame inside it. So for example if you have a GIF image which you want to watermark with a text its tough without a good editor.
Write text to Gif is one such utility which allows you to add text to GIF images and save it back as gif without loosing any kind of transparency or frames of that GIF image.
Just add any text and set the position of it and write. Once done that you can save it with a different name and use it like before.
