I think you misunderstand the purpose, Tikitiki. A forum icon manager let's you manage each image in the software that isn't like a background for each theme in one place, rather than having to dig through each template and find it. In this case, I don't think it even has the ability to upload - this just makes it a lot easier to change the name of an image file without having to find it in the templates. You can even change each one to text, or a URL not on the forum.
Personally, I like this idea - it would make it tons easier to change image names... but it would probably be better for 2.0 than 1.4.
