My layout of my thumbnail of Lightbox2 gallery looks fine in Firefox, not so great in Safari (See thumbnails. Have validated xhtml and css; now I'm testing browsers . Worried because I haven't tried the worst one yet (internet explorer) lol. So I'm on my way now to purchase virtual pc for loading windows on mac and testing it as read that angelwatt recons this is the best way for testing so it's from a very reliable source . Any input on this appreciated as always . Also if you look closely at the thumbnails the padding is fine on the first line and on the rest the last two thumbnails on the right have no padding .
