Re: Gap in images in table
Well, when I validate the page, there are errors around line 318 which is where a bunch of td/tr/table end tags are located. The fact that they are improperly nested (i.e. they are closed here but are not open) means they were probably improperly closed (or not closed) elsewhere.
But, just adding the
style="display: block;" to the <img> tags as sambauers suggested should take care of it without you having to fix the improper code. It should look fine when you do that and replace the stylesheet reference.
