transparent gif leaks beneath border?

[VaporAction]

is it possible for a gif's transparent background to extend past its border? when I say border, I mean the black border that frames the image in photoshop...

I ask because I seem to be getting a space beneath my image when I embed into my web page and I've taken care of the html side of things (all padding and margins set to 0px, etc.)...

When Photoshop exports a gif or a jpeg, BigData (the data that could extend over the image limits) is trimmed.
Is the image flattened before exporting to gif? Do you use Save for Web?

thanks Spectre...yeah, I think it was a css issue...I ended up just embedding the image differently...
