[jQuery] problem with hide()

[Nicolas]

Hello people; i'll go straight to my problem; when i load a certain
page inside it's $(document).ready(function(){ }); function i hide
some tables which (some) have images inside. The problem is that the
tables take a while to completly hide at the beggining, as i wish, and
take for a couple of seconds...; i need to know what am i doing wrong,
and how can i do those tables not to appear at the begging, many
thanks,
Nicolas.
