first off, you site looks fine & the same to me both in ie and ff.
second, to make an image 1px high add a style attribute to the image tag as this:
style="height: 1px;"
Dont' no what site you looked at but it is all messed up.
Plus it's nit the image height it's the cell height i been told to change so how do i do that?
same style attribute, only instead of putting it in the img tag put it in the tr tag.
pay notice that if the content of the cells don't fit in the height you set up it will resize itself so that content will show.
