What we want to do is to replace the image with the text in the variable $pod_frontheader.
(I don't think we really want to mess with tables)

My fix would then look like this:
# 1.80
$pod_line =~ s/<img SRC=\"\/odphead.gi.+?>/$pod_frontheader/i;

It seems to work on my site, but I am not sure that I haven't messed up anything else...
