Transparency and .vtf help

[Muffins]

I've been working on this spray for about a day now with some text and a transparent background, but whenever i save it as either .PNG .BMP. or .TGA (which are the 3/4 formats steam games can import) they always have a whitish/grayish background. Also I have these sick .GIF images that i wanna use, but when i Import it into VTFedit its just a still image. Is there any way to keep transparent backgrounds for one of the images that steam games can import(except for .vtf)?
And is there a way to make an animated .GIF into a .vtf without losing the animation and having a still image?

Thanks in advance

yes. put it into a png. import it through vtf editor and save as in your folder you desire. probly best to put in materials > Vgui > logos. and it should be transparent if not pm me
