Hi Ron,
Make sure you <img> tags include height= and width= attributes (which
match the acutal size of the graphic). This will allow most browsers to
layout and display tables before the image has been downloaded, as it
will already know how much space to allow. Similarly, hardcoding the
width of table cells can also help this pre-layout, as the browser
doesn't have to get the whole table downloaded to know size of each
column. I don't like this so much because I rely on the dynamic sizing
of table columns.
Also, breaking very long tables into a number of shorter ones can also
help.
Regards
Drew
