I've given up on the navigation buttons - it can be done but there is(was?) some hardcoded <nobr> tags that make things difficult - I haven't checked since 2.38 so maybe these are gone - I'll have to try again.
This is probably a waste of time - I want text for usability. As the gif is compressed and quick to render (probably quicker and more reliable than the style sheet) - all I should do is include an alt tag.
So I'd like to submit my change to the definition in the macro files;
<img src="/gsdl/collect/gsarch/images/gsarch.gif" border=0 alt="Greenstone Archives collection">}
