[thelist] ie5 mac: padding img

I'm trying to put space in-between these four images.  The CSS works fine
for the browsers I've tested except for IE5 for the Mac (and I'm assuming
Mozilla for the Mac too.)  I've tried the following:

#picmenu a {padding:0px 20px 0px 0px;}  (works in IE6/win,opera/win,etc.)
#picmenu img {...}
img#picmenu {...}
#bob2 img {...}
etc.
Any ideas?

Here's the code:
<div id="picmenu">
<h1>BUFFALO DAUGHTER</h1>
<p id="bob2"><a href="instore.asp?pic=bd1"><img
src="instore/buffalo_daughter_1_th.jpg" width="90" height="56" alt="Buffalo
Daughter"></a><a href="instore.asp?pic=bd2"><img
src="instore/buffalo_daughter_2_th.jpg" width="90" height="56" alt="Buffalo
Daughter"></a><a href="instore.asp?pic=bd3"><img
src="instore/buffalo_daughter_3_th.jpg" width="90" height="56" alt="Buffalo
Daughter"></a><a href="instore.asp?pic=bd4"><img
src="instore/buffalo_daughter_4_th.jpg" width="90" height="56" alt="Buffalo
Daughter"></a></p>
</div>

Thanks!
